Analyzing the minimum entrainment velocity of ternary particle mixtures in horizontal pneumatic transport

Thus far, studies on the effects of the polydisperse size distribution on the minimum particle entrainment velocity (UPU) in horizontal pneumatic transport are limited to binary mixtures of sandlike particles. Herein we experimentally investigate UPU of ternary mixtures involving large (i.e., 400 an...
