Numerical study on flow structure near two impermeable trapezoid submerged breakwaters on slop bottoms

摘要：

Studying on hydrodynamic characteristics in water waves propagating over two impermeable trapezoid submerged breakwaters is of great significance to research design and construction of this type of submerged breakwaters. The turbulent characteristics are discussed with cnoidal waves in the wave flume with 1:20 smooth slope.The governing equations of the vertical 2D model are the Reynolds-averaged Navier-Stokes equations. The Reynolds stress terms are closed by a nonlinear (anisotropic) k e - turbulence transportation model. Using a VOF method for tracking the free surface and source function wave generating method.Furthermore,the supplementary discussion is made by means of numerical results.
