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
When dlffuslon mslde the sohd particles which are dried m a fluldlsed bed can not be neglected this Internal ddTuslon can be accounted for by two mechanisms (a) the long term response which describes the gradual build up of a concentrahon profile inside the solid particles as function of the total d
## Abstract This article shows that spray nozzles pulsations can greatly improve the distribution of the sprayed liquid on fluidised bed particles, as characterised by a Nozzle Performance Index (NPI). Appropriate pulsations increased the NPI by nearly 100% under several operating conditions. This
