摘要：

Knowledge of the settling velocity of spherical particles in non-Newtonian power law liquids is required in design calculations for hydraulic conveying systems, using dense media, thickening and fluidization equipment, etc. In this work, an empirical formula has been developed which is explicit in velocity and reproduces a vast amount of data available in the literature. The scheme presented herein reproduces the results of nearly 400 individual sphere fall tests with an average error of 14% over wide ranges or rheological conditions and Reynolds numbers from 1 to 10(4).
