A stochastic model based on Markov chain is proposed to describe the gas residence time distribution and contact time distribution in multistage fluidised beds. The Kolmogorov-Feller equations are solved by Laplace transform and subsequent numerical inversion. The effects of flow fluctuations on the

Residence time distributions are required for modeling, design and optimization of chemical and biochemical multiphase reactors. Most models either cannot discriminate between true backmixing and a spread in fluid velocity or they require a large number of empirical parameters. A new stochastic mode
A stochastic model based mainly on a trivariate mean density function is proposed to describe an analogue form of a dispersed phase particle motion in Lhe upper region of an agitated vessel equipped with a turbine mixer. It is assumed that the particle motion is stopped at random time intervals by p
An experimental study was carried out to estimate the residence time distribution of low density particles injected into a fluidized bed reactor containing sand particles. Tracer experiments were performed at room temperature, using a pilot plant pyrolysis reactor. A novel technique was used to dete
