Modulating the mean residence time difference of wide-size particles in a fluidized bed
TL;DR: In this paper, the mean residence time (MRT) of coarse particles and the fine particles were investigated in a continuous fluidized bed with a side exit by varying the superficial gas velocity, feed composition and particle size ratio.

A model for residence time distribution in multistage systems with cross-flow between active and dead regions
J. Raghuraman,Y.B.G. Varma +1 more
TL;DR: In this paper, a three-parameter mathematical model for expressing the residence time distribution in multistage systems is proposed, in which a fraction of the feed short-circuits each stage consists of an active backmix region and a dead region with cross-flow of the material between the two regions.

Pressure drop of the fluid and the flow patterns of the phases in multistage fluidisation
TL;DR: In this paper, the authors discussed the theoretical models, experimental data and the range of applicability along with the correlations to predict the characteristics of the bed and discussed the correlations with respect to the theoretical model and experimental data.

An experimental investigation of the residence time distribution of solids in multistage fluidisation
J. Raghuraman,Y.B.G. Varma +1 more
TL;DR: In this paper, the cross-flow model was matched with the experimental data taken subsequently on the residence time distribution of solids in a multistage fluidised bed, and conditions for smooth fluidisation were suggested.
