Influence of cross-section shape on granular column collapses

We investigate granular column collapses with different cross-sections and associate the cross-section shape influence a finite-size analysis. Previous research, confined to initially circular configurations, reviewed importance of collapse studies concluded that run-out distance scales initial aspect ratio. In this work, columns three types (square, equilateral triangular, rectangular cross-sections) are simulated using discrete element method (DEM). explore how non-circular lead distances. Based on previously obtained analysis, we further link radius in directions relative size perform analysis explain influence. end, universal relationship, which includes frictional properties, sizes, influence, is proposed. Our results shown have direct relevance various natural engineering systems.
