Particle-resolved simulations of shock-induced size segregation*

Shock-induced particle-laden flow is observed in a multitude of natural and engineering applications and is often polydisperse. This study investigates the flow phenomena of shock-induced size segregation and dispersion of bidisperse particles using particle-resolved direct numerical simulations. We evaluate a simple model that provides a fundamental understanding of the essential forces that contribute to particle dynamics. In addition, we evaluate the ability of existing models to capture particle dispersion and size segregation within an Eulerian-Lagrangian framework.
