A Comparison of Correlations for Saltation Velocity in Horizontal Pneumatic Conveying

Abstract

Eight well-known published correlations for horizontal saltation velocity are compared using the accumulated solids-air data of many workers in the field. The correlation of Thomas (1962) is recommended as being the most accurate available for a priori prediction of saltation velocity. Other correlations tested were due to Zenz (1964), Matsumoto et al. (1974, 1975), Rizk (1973, 1976), Mewing (1976), Rose and Duckworth (1969), and Doig and Roper (1963).
