摘要

Coarse-grained (a.k.a. filtered) models for gas-particle flows strive to resolve coarse flow structures, while capturing the consequences of smaller scale processes through filter-size dependent closures. Through a combination of Euler-Euler and Euler-Lagrange simulations, we find that at small length scales the principal competition is between gravitational and particle phase stress, while at larger length scales it is between gravitational and particle inertia.
