Abstract

Liquid impact on a wall using a Finite Volume Element solver E. Bertolazzi Department of Civil and Environmental Engineering, University of Trento, Italy Abstract The numerical modeling of an inviscid dam-break surge as it advances over a dry bed and strikes a wall has been tackled in the literature, even though not within the framework of the potential flow model. The knowledge of the hydrodynamic loading due to this kind of impact has many practcal applications. The possibility to evaluate the global quantities of interest in the framework of the potential theory is explored in this work. The numerical method includes a potential flow solver coupled with an ordinary differential equation (ODE) solver. As a potential flow solver a Finite Volume Element method (FVE) is implemented. As ODE solver a second order Crank-Nicholson scheme is used. The FVE solver turns out to be second order accurate for the potential function and first order accurate for the flow field. Numerical tests indicated th
