✦ Synopsis

The wall effects on the terminal falling velocity of a sphere moving through power law liquids

(1 >~ n >~ 0.36) contained in a rectangular duct have been examined in the creeping flow region. Defining an effective diameter D e of the rectangular duct with a falling sphere, the experimental wall factor data have been correlated by means of a single relationship for rectangular ducts of arbitrary geometry including the parallel plates and square ducts.

This paper has been written to complement the paper by Cohen and Metzner (1981). These authors developed a parallel channel model of the packed column which they regarded as a porous medium divided into wall, transition and interior regions. Their model is comprehensive, but involves a substantial e
