In our latest work, we apply the z-transform technique to CFD simulations of reactive mixing unit operations. By postprocessing the CFD simulation data in z-space, we can construct transfer functions for the transported reactive chemical species that are, by design, functionally equivalent to the linear finite-volume discretized equations that comprise the full-scale CFD model. These transfer functions can then be used to generate additional data for analysis with much less computational effort. In this presentation we illustrate this technique using an example of a continuous stirred-tank reactor (CSTR) with a first-order chemical reaction and show that the results obtained using faster z-transform technique are practically identical to the results obtained using fully detailed CFD simulations.
