IMPULSE RESPONSE OF A MIXING MODEL CONSIDERING THE FLUID EXCHANGE BETWEEN UP- AND DOWN-FLOWS

[摘要] References(7)Cited-By(1)A mixing model that assumes two regions of upward and downward plug flows in a batch reactor and exchange of fluid between them is presented and its impulse response is solved by a Laplace transformation. When exchange rate is low, the impulse response curves are stepwise and when high, the curves are smooth. The calculated responses compare satisfactorily with the experimental responses in a bubble column.
