Abstract
  • The water flow after the sudden break of a dam is schematically represented as an initially rectangular column of luid supported by a horizontal bottom, limited by a wall on one side and free to evolve on the other one. The flow is characterized by the development of a toungue of liquid quickly spreading along the horizontal boundary without any sign of free-surface breaking. This problem has been widely investigated numerically because, besides its practical meaning, it is a clean test case to verify and validate methods handling large deformations of the free surface. Here, we present a comparative study between 1) the Boundary-Element Method for potential flow, 2) the Smoothed Particles Hydrodynamics method for the Euler equations, and 3) the direct solution of the Navier-Stokes equations coupled with the Level Set method for the capturing of the free surface.
