Numerical modeling of submarine mass-movement generated waves using RANS model

摘要

In this paper a numerical model for predicting waves generated by nearshore submarine mass-movements is described. The model is based on the Reynolds averaged Navier-Stokes (RANS) equations with the k-epsilon turbulence model. The volume of fluid (VOF) method is employed to track the free surface. Numerical results obtained from the present model are validated with laboratory experiments and analytical solutions. Very good agreements are observed for both submarine and aerial mass movements. Numerical experiments are performed to obtain the empirical formula for the maximum runup and rundown as functions of slide properties. (c) 2006 Elsevier Ltd. All rights reserved.
