First Exit Time of Markov Processes for Particle Transport in Fluidized Bed Reactors

摘要：

In this paper we study a Markov process that has been proposed by Dehling,Hoffmann and Stuut(1999)as a model for particle transport in fluidized bed reactors.We propose different boundary condition at the exit of the reactor that captures the fact that particles cannot leave the reactor bv diffusiou.and the net downward drift is related to the volume balance.In the discrete model,we show that processes satisfv Danckwerts’Iaw,stating that the expected first exit time equals Ⅴ/V where Ⅴ denotes the volume of the reactor occupied by the fluid and V the volumetric inflow rate.In order to ease and double check the prooL we use Maple for mechanical support.
