This paper discusses a comparison of the data of experiments obtained by using different shear tests methods in order to examine the confidence in the results of experiments on the flow properties of a bulk solid. The angle of internal friction of dr

In this paper we present a model for determining the performance behavior of a CFB reactor. This model is not sophisticated and does not require computer calculations, but is realistic and convenient for engineers engaged in the development of new pr

The heart of this novel rotary contactor is the inclusion of a longitudinal partition plate and a series of guide plates. The contractor is kept horizontal, not inclined, and the placement of the guide plates can cause the solids to move in one direc

This paper develops a flow and contacting model to represent a CFB. Best estimates of contacting efficiencies are presented for the turbulent, fast fluidized, and pneumatic transport regimes of the CFB. Material balances are presented, ending up with

In Part I, a set of differential equations is solved to account for the partial separation and reflux of solids from the bed exit, giving working equations to predict the vertical distribution of solids throughout the freeboard. This reflux is accoun

A flow model is proposed to investigate the transition of flow regime from bubbling to turbulent fluidization postulating that the flow in the emulsion phase follows the Richardson-Zaki equation. Void fraction of the whole bed ef and the mean velocit

Experiments in bubbling fluidized beds show that gases which adsorb on solids experience up to ten times more rapid bubble-emulsion interchange than do nonadsorbing gases. We propose that the very small fraction of solids dispersed in and passing thr
