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...

Inferring the Distribution of Households' Duration of Residence from Data on Current Residence Time

Residence time distribution for a class of Gaussian Markov processes.

We study the distribution of residence time or equivalently that of "mean magnetization" for a family of Gaussian Markov processes indexed by a positive parameter alpha. The persistence exponent for these processes is simply given by theta=alpha but the residence time distribution is nontrivial. The shape of this distribution undergoes a qualitative change as theta increases, indicating a sharp...

Characterizing continuous powder mixing using residence time distribution

Continuous powder mixing is an efficient alternative in high volume manufacturing of powder-based products. A new method is communicated in this paper to determine the effects of different operating conditions andmixer configurations onmixing performance. Themain idea of the proposedmethodology is the utilization of experimental residence time distribution (RTD) measurements to (a) determine th...
