Compressible pairwise interaction extended point-particle model for force prediction of shock-particle bed interaction

Abstract

Euler-Lagrange simulations are often required to study complex compressible multiphase problems. Such systems include volcanic explosions and supernovas. We developed an unsteady neighboring particle interaction framework with the help of the compressible Maxey-Riley-Gatignol equation and the scattering theory, which further improves force predictions used in Euler-Lagrange simulations.
