Abstract

A new modification of algorithm for direct numerical simulation of dispersed admixture dynamics in heterogeneous flows is presented. Distinctive feature of this method is a combination of direct simulation of particles collisions using trajectory approximation and conception of probe particles.

Keywords:

multiphase flows; direct numerical simulation; discrete-element method; fullscale modeling; probe particles
