Investigating the effect of flow direction on suffusion and its impacts on gap-graded granular soils
TL;DR: In this article, a coupled computational fluid dynamics and discrete element method approach is presented to simulate the particle-fluid interaction relevant to this problem, which is first benchmarked by a classic granular system problem, then used to investigate the characteristics of suffusion and its impact on the mechanical behavior.
