Abstract

Multiphase flows involving granular materials are complex and prone to pattern formation causedby competing mechanical and hydrodynamic interactions. Here we study the interplay between granular bulldozing and the stabilizing effect of viscous pressure gradients in the invading fluid.Injection of aq...
