ALES SHALLOW-WATER FLOW SOLVER WITH NON-HYDROSTATIC PRESSURE: WAVE APPLICATIONS

J.G. Zhou, P.K. Stansby

Abstract


A shallow-water flow solver with non-hydrostatic pressure in a coordinates has been developed to include effects due to the moving grid, referred to as the ALES approach. The formulation is outlined for 2D vertical plane problems and tested against experimental data for wave flows over plane beds, bars and trenches. Agreement with experiment is generally good and the importance of non-hydrostatic pressure and moving-grid terms is demonstrated.
