Nonlinear frequency response analysis of forced periodic operations with simultaneous modulation of two general waveform inputs with applications on adiabatic CSTR with square-wave modulations
Nonlinear frequency response (NFR) method was used to evaluate the forced periodic operations and
their potential for improving the system performance compared to steady-state operations. The NFR
method was used to evaluate the time-average performances of forced periodically operated systems
subjected to simultaneous periodic modulation of two-inputs of general waveforms. As an example, a
forced periodically operated adiabatic CSTR with simple nth order reaction A ? mPP and square-wave
modulation of two pairs of inputs were analyzed in detail. The theory is illustrated analyzing the hydrolysis
of acetic acid anhydride performed in a laboratory scale adiabatic CSTR. The results showed that significant
improvements could be achieved by simultaneous modulation of both pairs of inputs.
Comparison with the results of numerical integration showed that the approximation using only the
asymmetrical second order FRFs and the first three harmonics of the inputs provide very reliable pr...edictions
of the DC component.
