A Model For The Residence Time Distribution and Holdup Measurement in a Two Impinging Streams Cyclone Reactor/Contactor in Solid-Liquid Systems

In this paper a two impinging streams cyclone contacting system suitable for handling of solid-liquid systems has been studied. Certain pertinent parameters such as: solid holdup, mean residence time and Residence Time Distribution (RTD) of solid particles have been investigated. A stochastic model based on Markov chains processes has been applied which describe the behavior of solid partic...

Using Residence Time for the Extraction of Recirculation Regions

This paper introduces the concept of residence-time, from the Eulerian view point, in a rigorous manner. The equations for various ow regimes are derived and a numerical solver is introduced based on Lax-Wendroo integration. An implementation is discussed that allows the coupling of this solver to any explicit CFD code. Examples of this concept are shown for extracting recirculation regions by ...

Residence Time Distribution for Tubular Reactors

In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactor, in general, are treated ideally: mixed and plug-flow patterns. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal reactors is used, among others, residence time distribution function E(t), mean residenc...
