Abstract

For downflow of cohesive solids in a standpipe in the absence of pressure gradient, the flow, no-flow criterion of Jenike (1964) can be applied to determine the minimum diameter for no arching to occur. In this paper Jenike's analysis is extended to account for the presence of pressure gradient in the standpipe. An equation for estimating minimum pipe diameter for smooth flow is presented. For design we suggest that the minimum diameter in the absence of pressure gradient should be measured and our equation is to be applied to extrapolate to the real situation with a finite pressure gradient. The present work is relevant to recent usage of standpipes in oil-shale processing and coal power plants. © 1983.
