Abstract
In this paper, a free surface numerical technique is validated by comparing numerical and experimental results of cylindrical flows involving impact between a fluid and a solid obstacle. Numerical simulations are presented for an axisymmetric, high-speed flow during which impacts occur and the free surface changes shape dramatically. The numerical results of a flow over a dike possess the same open dome-like fluid structures observed in experiments, thus providing strong validation for the numerical technique. The manner in which the fluid surges over a given dike depends strongly on the prescribed fluid height. Different overflow fluid structures that lead to large overspills are identified.
