Effects of specularity and particle-particle restitution coefficients on the recirculation characteristics of dispersed gas-particle flows through a sudden expansion
We numerically investigate the effects of restitution and specularity coefficients on the
characteristics of dispersed gas-particle flows through a sudden expansion. The studies are
carried out using an indigenous finite volume flow solver in a collocated framework with two-
fluid model. Parametric studies are performed to gain insights into the differences in
recirculation patterns that arise due to variations in restitution and specularity coefficients.
The simulations show that particle-particle interactions, quantified by restitution coefficient …
