POWER REQUIREMENTS IN THE AGITATION OF NON-NEWTONIAN FLUIDS

Abstract

A modified Reynolds number in the agitation, based on the Ellis and Sutterby models of three rheological constants for non-Newtonian fluids, is defined in the way that the relation between friction factor and Reynolds number in the case of non-Newtonian pipe flow may be the same as that in the case of Newtonian pipe flow.
Introducing this modified Reynolds number, the same correlation of the power requirements can be applied to both experimental results of Newtonian and non-Newtonian fluids with various types of impellers.
