Numerical Simulation of Irregular Breaking Waves Using a Coupled Artificial Compressibility Method

Wave breaking is widely recognized as a very challenging phenomenon to emulate using numerical/computational methods. On that condition, the transition from modelling regular irregular waves not trivial. Even though some issues are surpassed in CFD simulations, there still two substantial problems account for. The first one entails proper generation of numerical wave tank, while second introduction turbulent regime solver. present work addresses these by employing Stabilized k?? SST model for turbulence closure and proposing an efficient accurate method generation. Apart that, artificial compressibility used coupling system equations, which solves equations non-segregated manner overcomes pertaining existence interface free-surface flows. methodology validated through test case propagation over submerged breaker bar piecewise sloped bottom, indicating ability capture phenomena. Simulations fair agreement with experimental data regarding energy spectra free surface time-series, results suggest known over-prediction kinetic (TKE) significantly constrained stabilized model.
