Dynamics of Gas-Solid Semi-Fluidization of Binary Homogeneous and Heterogeneous Mixtures

Abstract

The necessity of generalized correlations relating to the dynamics of gas-solid semi-fluidization of homogeneous and heterogeneous mixtures has been emphasized. Based on dimensional analysis approach, equations have been developed for the prediction of minimum and maximum semi-fluidization velocity and semi-fluidized bed pressure drop for the above-mentioned systems. Equations have also been proposed for minimum fluidization velocity. A fairly good agreement has been obtained from the various calculated and experimental values.
