Downslope granular flow through a forest of obstacles

Year: 2023

Type: article

Abstract: This work investigates the role played by a forest of pillars on the steady flow of a granular layer down an inclined plane. We realized experiments for different inter-pillar distances to observe how the forest density slows down the granular flow. These observations are rationalized by an average approach that considers a granular rheology for the flow and includes the additional force exerted by the pillars on the granular layer.
