Abstract

Within the framework of the mechanics of heterogenous media, the flow of a mixture of high-pressure gas and an initially close-packed disperse phase from a cylindrical channel of finite dimensions into the atmosphere is investigated numerically. The physical picture is analyzed and the characteristic stages of the process are established. Experimental data indicating satisfactory agreement between the mathematical model and the phenomenon investigated are presented.
