Numerical simulation of wave breaking in shallow waters by using a SL-VOF method

摘要

Numerical simulations of wave breaking in shallow waters have been performed by using the finite volume fluid mechanics code "EOLE" developed by Principia R&D. To this threedimensional, curvilinear, multidomain model has been added an original Segment Lagrangien - Volume Of Fluid (SL-VOF) method, very accurate when dealing with highly non linear interfaces. Results concerning the interface evolution, the velocity and pressure fields in the shoaling zone and in the surf zone are presented for a solitary wave normally incident on bottoms of constant slope. The results are successfully compared with those obtained by numerical models based on the Boundary Integration Element Method (BIEM).
