Dynamic Mesh-Based Modeling of Turbulent Flow Effects on Concentrated Leak Erosion during HET

Abstract:

This study examines numerical modeling of concentrated leak erosion in cohesive soils under turbulent flow conditions using the Hole Erosion Test (HET). Internal erosion, where soil particles detach due to subsurface flow, significantly weakens structures like dams and dikes, potentially causing floods.The study made a model to show erosion using changing meshes at the spot where water meets soil. It uses rules based on key shear force and erosion numbers. The model was tested for pipe erosion in 2D with slow water. It was then checked against the HET model. Two different soils were tested successfully using this approach, followed by a study to see how erosion factors change erosion speed and channel size. This model was proved to work when looking at experiments and Bonelli's papers. It shows leak erosion well while giving helpful flow data to better know how erosion works.
