Prediction of Onset Semifluidization, Maximum Semifluidization Velocities and the Packed Bed Height

Abstract

INVESTIGATIONS on semifluidization reported already have been briefly summarized. Experimental data for a few water-solid systems have been obtained. Correlations have been developed for the prediction of the onset of semifluidization velocity, the maximum semifluidization velocity and the height of packed bed formation from the properties of the liquid and solid particles and the position of restraining screen. The observed values are compared with the values calculated by the equations suggested.
