AB  - A multidisciplinary research method was employed with the intention to create a series of bio-inspired flattened airfoils, observe their aerodynamic characteristics, and analyse their applicability to small devices or to designs of high-speed trains, within the shortest period in the conceptual stage. A research specimen of a kingfisher, selected for biomimicry, was examined with the following methods: visual inspection, analysis of photographs, manufacturing quality control measurement with a 3D laser scanner, and microscopy. A basic multi-arc-line profile, re-engineered from the overlapped specimen shape data and based on the observations, was used for designing a series of seven derived airfoils. The aerodynamic characteristics of the bio-inspired airfoils were obtained with the panel methods at low and moderate subsonic speeds, while the small transonic difference method was used in the high-subsonic speed range. Basic and ellipse-like airfoils produce higher total drag at low and moderate velocities and higher forebody drag in the high-subsonic range when compared to derived and parabola-like airfoils. The obtained critical Mach numbers are in the range from 0.76 to 0.78, where three bionic airfoils show values equal to or smaller than the values of ellipse- and parabola-like airfoils. The profile with the shortest bio-inspired relative chord has a higher critical Mach number value than the parabola-like profile. The sonic lines above these profiles appear at close positions. The applied set of examination methods of the bio-inspired design is not time consuming and produces sufficiently good results in the conceptual stage. Therefore, a further development of unique and adjusted numerical methods and codes at pre-computational fluid dynamics run is encouraged, together with shape parameterization.

AB  - The corrosion behavior of AA7049 aluminum alloy in NaCl solution in the presence of environmentally-friendly corrosion inhibitors (Ce-chloride, Ce-formate, Ce-acetate, and Ce-propionate) was analyzed. The chemical composition of intermetallic particles was evaluated by a Scanning Electron Microscope, equipped for Energy Dispersive Spectroscopy measurements, while the presence of cerium and type of functional groups in inhibitors surface layers were analyzed by X-ray Photoelectron Spectroscopy and Fourier-Transform Infrared Spectroscopy, respectively. Inhibitor efficiencies were tested by applying electrochemical techniques such as Electrochemical Impedance Spectroscopy and Linear Sweep Voltammetry. Ce-propionate showed a greater inhibitory effect than all other tested corrosion inhibitors. The inhibitory effect decreases in the following order: Ce-propionate > Ce-acetate > Ce-formate > Ce-chloride. Propionate anions have a higher water contact angle and also a longer aliphatic side chain than acetate and formate anions. The mechanism of inhibitory action of Ce-propionate and other tested corrosion inhibitors has been proposed.

AB  - This paper presents a study of a free convection flow around the walls of a ventilation mill of the Thermal Power Plant “Kostolac B”, Kostolac, Serbia. A combined method consists of thermography and software post-processing, PATS. The PATS is specially developed for recognition of turbulence zones by the custom processing of large input data sets from thermal videos. The calculations determine maximum temperature fluctuation i.e. peak-to-peak fluctuation at every spot during the recording time. Three thermal videos of the walls were analyzed. Maximum temperature fluctuation occurred in the zones close to the obstacles, which are thus recognized as one of the main sources of turbulence. Besides, PATS has recognized fine camera oscillations and mechanical movements of a flexible material near the dozer wall. The detected zones of turbulence correspond to the previous studies and to the theory. The method shows good potential in the field of free convective flow research through the improvement of testing efficiency and cost savings. State-of-the-art thermograph cameras and updated software are recommended.

AB  - The removal of varnish is a very challenging task in the conservation of wooden artifacts. The results of experiments performed to investigate the suitability of lasers for cleaning aged varnish from bog oak wood (ebony) are presented in this paper. Optimal laser parameters for safe and efficient varnish ablation were determined in order to preserve the integrity of the original wooden substrate during the cleaning process. The ablation threshold for varnish and wood damage threshold was examined using Nd:YAG laser (1064, 532 and 355 nm) emitting pulses of nanosecond (8 ns) duration. Results of induced varnish removal and other morphological alterations to the wood surface were investigated by optical microscopy and colorimetry.

AB  - The  modern  military  industry  demands  the  most  innovative  and  high-quality  metals  and  alloys,  as  well  as 
processing technologies. Iron and its alloys are a common material used for different types of weapons and military 
equipment. Lasers have been widely used in the metal surface processing, but the changes that occur on laser treated metal 
surfaces have not yet been sufficiently investigated. A study of morphological and chemical changes on the metal surface 
induced by Nd:YAG laser treatment in ambient air is presented. A pulsed Nd:YAG laser (1064 nm, Gaussian spatial profile, 
FWHM  8 ns, energy up to 525 mJ, beam diameter of 1-10 mm and fluence up to 3.5 J/cm
2
) was used.  Micro-morphological 
analyses of sample surfaces before and after laser treatment process were performed by optical and SEM microscopies. 
EDX method was used for chemical analyses and Spectra colorimeter for investigation of induced color changes. The laser 
irradiation effects were studied as a function of two laser parameters, number of laser pulses and laser fluencies, around 
and over the damage threshold. The results show that there are significant differences depending on these laser parameters.

AB  - In the times of significant development of high-speed train transportation and taking the primacy over the others. One of the major designing task is to predict accurately and fast the vehicle main performances, especially aerodinamics. Motivated by the bionic design of representative Japans train Shinkansen, the presented bionic design was based on the observations of the kingfisher from Serbian national heritage collection. The specimen beak shape has been measured by laser scanning, and converted to a mesh. Afterward, the longitudinal cross-section of the beak was implemented to a bionic high-speed train design. As the critical, the conditions of the trains forehead entering into the tunnel were selected, while the case scheme employed relative motion. The forehead contour distributions, obtained with computational fluid dynamics, were used for the prediction of the transition zone extension. The anomalies in surface temperature behavior were additionaly analyzed by pressure and density distribution inside the tunnel and over the forehead. Besides the gross time history of the pressure derivative of time is in correspondance with the referent, it was interpreted that the true biological form is not fully suitable for adoption for bionic design. The development of this design, employing contour simplification by the close parabolic function will continue in the future. This work suggests an ecconomic and efficient approach to analyze the results of the Reynolds-Averaged navier-Stokes equation adeqate for the concept design stage.

Besides the gross time history of the pressure derivative of time is in correspondance with the referent, it was interpreted that the true biological form is not fully suitable for adoption for bionic design. The development of this design, employing contour simplification by the close parabolic function will continue in the future. This work suggests an ecconomic and efficient approach to analyze the results of the Reynolds-Averaged navier-Stokes equation adeqate for the concept design stage.",

AB  - The paper analyses the corrosion behaviour of naturally and artificially aged
AA2024 alloy in NaCl solution and in the presence of an environment ‐ friendly
corrosion inhibitor, CeCl 3 . On the basis of the values of polarisation resistance
and  corrosion  current  density,  the  corrosion  resistance  of  the  protective
inhibitor film is established as well as the general corrosion resistance of this
aluminium  alloy.  Resistance  to  pit  formation  is  determined  based  on  the
difference in pitting and corrosion potentials while resistance to pit growth is
determined based on the amount of charge consumed during pit growth. A
scanning electron microscope is used to examine the morphology of the pits
formed during the pitting corrosion testing, as well as to determine the cerium
content on intermetallic particles and the matrix AA2024 alloy. The corrosion
behaviour of AA2024 alloy is investigated after different test periods in NaCl
solution  and  in  the  same  solution  with  the  CeCl 3 inhibitor.  The  corrosion
resistance of both tempers of AA2024 alloy is more than one order of magnitude
higher in the presence of CeCl 3 . An explanation of the observed differences in
the corrosion behaviour of the naturally and artificially aged AA2024 alloy is
proposed. Different corrosion behaviour of the alloy after different test periods
is also explained.

AB  - The investigations of the turbulence in the flow are one of the most expensive, thus the improvement of existing ones and the research related to the new methods are in continual development. The multidisciplinary approach led to the application of the infrared thermography in the turbulent boundary layer observations with the endpoint goal of energy and cost savings in its early stages. This work presents the use of the industrial type infrared thermography for identification of the turbulent zones in the free convective flow, so far the less investigated problem related to convection heat transfer. It was shown that the transient spot temperature difference, measured on the complex geometry of the real-scale coal ventilation mill, of the Thermal plant “Kostolac B”, by an infrared camera, is a good parameter for identification of the most influenced positions by turbulence. The defined fields with maximal transient temperature difference are in accordance with theory and values calculated by numerical simulations for clean geometry, confirming the assumptions. The described method is also convenient for use in cases when the other methods are not applicable because of the complex geometry, unapproachable, or for the other similar reasons. The results from this work would support the more precise measurements with the research type infrared camera, the other methods for measurements.

AB  - The paper presents the results of laser cleaning of corrosive and other deposits on a metal archaeological artefact from the Danube. Nd: YAG laser, energy up to 750 mJ and wavelengths λ = 1064 nm and 532 nm is used. The cleaning efficiency was examined in the function of laser energy, wavelength, and number of pulses, i.e. the time of exposure and moist of the surface of the sample. The results of removal of unwanted layers from the surface of the artefact and morphological changes on the base material were examined by optical and scanning electronic microscopy (OM and SEM). Micro-chemical changes have been determined by energy dispersive X-ray analysis (EDX) and x-ray fluorescence spectrometry (XRF). It has been shown that λ = 532 nm has higher efficiency for cleaning this sample and that the surface moisture has very small influence on laser cleaning efficiency. Research carried out on the archaeological object from the Danube shows that the application of lasers in the cleaning of undesirable layers is very efficient, safe and environmentally friendly.
AB  - U radu su prikazani rezultati laserskog čišćenja korozivnih i drugih naslaga na metalnom arheološkom predmetu koji je nađen u Dunavu. Korišćen je Nd:YAG laser, energije do 750mJ i talasne dužine λ=1064nm i 532nm. Efikasnost čišćenja je ispitivana u funkciji energije lasera, talasne dužine, broja impulsa, odnosno vremena eksponiranja i vlažnosti površine uzorka.

abstract = "The paper presents the results of laser cleaning of corrosive and other deposits on a metal archaeological artefact from the Danube. Nd: YAG laser, energy up to 750 mJ and wavelengths λ = 1064 nm and 532 nm is used. The cleaning efficiency was examined in the function of laser energy, wavelength, and number of pulses, i.e. the time of exposure and moist of the surface of the sample. The results of removal of unwanted layers from the surface of the artefact and morphological changes on the base material were examined by optical and scanning electronic microscopy (OM and SEM). Micro-chemical changes have been determined by energy dispersive X-ray analysis (EDX) and x-ray fluorescence spectrometry (XRF). It has been shown that λ = 532 nm has higher efficiency for cleaning this sample and that the surface moisture has very small influence on laser cleaning efficiency. Research carried out on the archaeological object from the Danube shows that the application of lasers in the cleaning of undesirable layers is very efficient, safe and environmentally friendly., U radu su prikazani rezultati laserskog čišćenja korozivnih i drugih naslaga na metalnom arheološkom predmetu koji je nađen u Dunavu. Korišćen je Nd:YAG laser, energije do 750mJ i talasne dužine λ=1064nm i 532nm. Efikasnost čišćenja je ispitivana u funkciji energije lasera, talasne dužine, broja impulsa, odnosno vremena eksponiranja i vlažnosti površine uzorka. Rezultati skidanja nepoželjnih slojeva sa površine uzorka, kao i morfoloških promena na osnovnom materijalu, ispitivani su optičkom i skenirajućom elektronskom mikroskopijom ( OM i SEM), a ispitivanje mikrohemijskih promena izvršeno je pomoću energijske disperzione spektrometrijske analize (EDX) i rendgensko fluorescentnom spektroskopijom (XRF).

AB  - Methods of diagnosing aerodynamic characteristics are constantly developing in order to conduct the precise and energy efficient wind tunnel testing of transport vehicles in the prototype design early stages. This is of a special importance when facing the time/cost consumption problems of detection of the transition zone over the simplified design of the high-speed train. Herein the applied thermodynamics found a very significant role in the field of experimental aerodynamics. With the intention of detecting the boundary-layer transition zone the following measurements were applied: the infrared thermography, flow visualization, and drag force measurements. In addition, the CFD was applied to predict the flow behaviour and transition zone, solving PDE consisting of the Reynolds-averaged Navier-Stokes equations, energy equation, and the equation of state for an ideal gas employing density-based solver. The thermal imaging defined the transition zone by simple application, and fast recognition, while the transition bounds were defined in the analysis. The flow visualization confirmed thermography results and the method itself as favourable, especially in the most expensive early phases of redesigning for aerodynamically optimized and energy efficient solutions. The numerical method was confirmed by the experiments, resulting in acceptable differences in the definition of the transition zone. For a better understanding of the phenomenon, the overlapped implementation of the presented methods focused on forced convection showed as the best solution. Based on the experiences of this research, development of the additional equipment and adjustments will be introduced in the future experiments.

AB  - Numerical simulation of 3D multiphase flow is performed to determine the velocity field in the fan mill. The mixture model of the Euler-Euler approach is used. Recirculating gas is a primary phase that carries granular phases including the coal powder and sand. The latter causes heavy wear of mill impact plates. The optimal form of hardfacing geometry and technology has an impact both on velocity magnitude and direction of flow in such a way as to reduce plate wear. This paper presents results of surface modification (based on numerical simulation), implemented on impact plates of the fan mill in the Kostolac B power plant in Serbia. Fishbone hardfacing is made in order to increase the lifetime of impact plates and extend the period between overhauls of fan mills. The experimental tests of fishbone surfacing plates, in exploitation conditions, show that the applied modification, hardfacing technologies and coating materials, give expected results. The application of this hardfacing in the form of a fishbone is simpler, faster and more economical compared to complete overlaying and honeycomb impact plate surfacing. The relative weight loss of base plate after an 1440-hour period of exploitation is 8%, while the weight losses for the hard-faced plate is below 7%.
