NUMERICAL SIMULATION OF BREAKING WAVES BY LARGE EDDY SIMULATION AND VOF METHOD

Qun Zhao, Katsutoshi Tanimoto

Abstract


In this paper, the VOF method for free surface flow is applied to simulate breaking waves incident on a submerged reef. An efficient numerical wave channel with two absorbing boundaries is developed. Corresponding boundary conditions are prescribed. Smagorinsky's sub-grid scale model is incorporated to account for the sub-grid scale turbulence. Numerical results are compared with laboratory measurements.
