Title: Simulation of Dam-break Flow with Smooth Particle Hydrodynamics
Author(s): Bogdan-Alexandru Belega                        

Abstract: In the present work an approach to solve numerical modelling of water flow which is generated by the break of a dam. The governing equations are solved by applying a smoothed particle hydrodynamics (SPH) method in which standard smoothing kernel functions and their gradients are satisfied. The presented SPH model has been used to simulate a two-dimensional problem of the collapse of a water column. The numerical simulations reveal the formation and propagation of a wave over the horizontal plane. There are simulated and presented the model predictions of the changes of the moving wave-front position and the changes of the free surface elevation of water. The results of the numerical simulation with the corrected SPH method are compared with those given by the standard SPH method without kernel correction.

Keywords: SPH (smoothed particle hydrodynamics), numerical simulation, Lagrangian method, fluid flow, dam break.
