A New Cavitation Simulation Method: Dam-Reservoir Systems

Abstract

Based on one-fluid cavitation model, a novel finite element method for the simulation of acoustic cavitation is presented. The proposed approach is used to investigate cavitation effects on dynamic response of concrete dams. The resultant nonlinear equation of motion of fluid domain is discretized using a pressure-based finite element method and a standard displacement-based finite element formulation is used to discretize linear equation of structure motion. An iterative partitioned solution method is applied for the simultaneous integration of coupled equations.
