Pressure drop and limit deposit velocity for solid-liquid flow in pipes

Abstract

Experimental data of pressure drop and flow patterns for the pipe flow of solid-liquid mixtures were obtained. Special emphasis was put on the range of low mixture flow rates, where a stationary bed is expected. The new experimental data and other data from the literature compare favorably with the three-layer model of Doron and Barnea (1993, Int. J. Multiphase Flow 19, 1029–1043).
