Abstract

Deviations from plug flow are handled by a Monte Carlo model which simulates mixing and segregation effects in a tubular chemical reactor. The model superimposes dispersion, which is simulated by local droplet coalescence, on the plug-flow mean velocity. Both the residence time distribution and the micromixing details are determined by the local coalescence-mixing phenomena. The model is applied with success to the experiments of Vassilatos and Toor. Comparisons are drawn between this and other models. Use of the model is suggested whenever deviations from plug flow are present in conjunction with segregation effects and rapid of two miscible fluids with mixed or unmixed feed. Further use should be possible with coalescence two-phase extraction and reaction systems.
