Effect of particle insertion rate and angle of insertion on segregation in gravity-driven chute flow

Particulate segregation shows many problems during particulate processing in many industrial applications and in many geophysical flows. Hence, it is very desirable to understand the mechanism of segregation and simultaneously to minimize the segregation. We investigate the effects on segregation in a gravity-driven granular chute flow when a 3rd species is added to a binary mixture. We systemically varied the rate of particle addition and the angle of particle addition to observing their effect on the mixture segregation. Generally, for all inclinations simulated, we found that the tendency of segregation decreases to some extent when we increase the rate of particle addition and when the injection angle is in the opposite direction as bulk particle flow.
