SPECIFIC EDDY VISCOSITY FOR WAVE BOUNDARY LAYERS: CALIBRATION BY A TWO EQUATION k-ω MODEL
Résumé
The aim of our study is to improve the prediction of SSC in wave boundary layers by using simple analytical tools which take into account the more important involved physics, for practical use in coastal engineering. Our study will show that: - For practical applications the period-averaged eddy viscosity could be described by a simple analytical formulation (Absi, 2010) - The shape of the analytical period-averaged eddy viscosity formulation will be validated by BSL k-ω model (Suntoyo and Tanaka, 2009) for sinusoidal (figure 1) and asymmetric waves - Period-averaged eddy viscosity profile depends on the wave non-linearity parameter and requires therefore a specific calibration.
