Prediction of Dam Break Hydrodynamic Wall Pressure

摘要

In this paper, hydrodynamic wall pressure resulting from a dam break simulation is analyzed in detail. The simulation has been done real-time in three dimensions using an innovative particle-cluster approach that is able to simulate complex liquid dynamics in much shorter time than classical continuum mechanics approaches. The results for impact pressure, water height and wave speed are in very good qualitative and quantitative agreement with results from experiments and CFD solutions carried out at Groningen University. Special focus has been set on the unsteady wall pressure distribution during initial and reflection wave impact.
