Wall effects on the velocities of a single sphere settling in a stagnant and counter-current fluid and rising in a co-current fluid
(Elsevier Science Sa, Lausanne, 2010)
Experimental results were obtained on the steady settling of spheres in quiescent media in a range of cylindrical tubes to ascertain the wall effects over a relatively wide range of Reynolds number values. For practical ...
Mass transfer and concentration boundary layer in a particulate fluidized bed
(Elsevier, 2016)
The aim of this study was to analyze the concentration boundary layer for a comprehensive description of the mass transfer in systems with fluidized particles. Mass transfer from the wall of the column to the fluid in the ...
Optimal pixel resolution for sand particles size and shape analysis
(Elsevier, 2016)
In this paper, the influence of different scanning resolutions and the use of image analysis softwares for the image analysis, SigmaScan Pro, Image) and Matlab, on size and shape factors commonly used in particles ...
Particle characterization of polydisperse quartz filtration sand
(Elsevier, 2014)
In this paper, different methods for particle characterization were applied to 16 polydisperse fractions of quartz filtration sand obtained by sieving, with sieve diameters in the interval d(m) = 0359 to 2.415. For each ...
Hydrodynamic modeling of downward gas-solid flow. Part II: Co-current flow
(Elsevier, 2014)
The one-dimensional model of accelerating turbulent downward co-current gas-solid flow of coarse particles was formulated and experimentally verified by measuring the pressure distribution along the transport tube. The ...
