Some characteristics of flow past bodies moving in two-phase media 'gas-solid particles' in the case of particle fractionation
Abstract
Flow past moving rigid bodies in two-phase media is examined with allowance for the effect of solid particle fractionation using experimental data obtained for a 10-mm-diameter polished steel ball moving at 800 m/s in a gas containing bronze and electrocorundum particles. It is shown that the combined effect of particle fractionation, entrainment of the finest particles, and interaction with noncollided particles leads to an increase in the concentration of the fine fraction. The inverse effect of the deflected particles on the head shock is discussed.
