Predictive capability of computational fluid dynamics simulations for the prediction of plunging breaking wave is assessed. Laminar flow simulations are performed for dam break, solitary wave run up on a slope and flow over a submerged bump using OpenFOAM, a finite volume solver with volume-ofluid (VoF) interface capturing method, and Proteus, a finite element solver with coupled level-set/ volume-ofluid (CLSVoF) methods. CLSVoF predicts wave elevation before the plunge, and primary and secondary plunger shapes better than VoF in all the cases. The primary limitation in the simulation is the airflow, which results in diffused plunger tips in VoF simulations, and results in surface peel-off in CLSVoF simulations. Future work should include 3D turbulent flow simulations.
