Abstract EN
This paper simulates regular waves propagating over a submerged parabolic obstacle in the presence of a uniform/shear current using a two-dimensional numerical model, named COBRAS (Cornell Breaking and Structure).
The numerical model solves the Reynolds-Averaged Navier-Stokes (RANS) equations and the free surface deformation is tracked using the volume of fluid method (VOF).
The capability of the numerical model to simulate regular waves with a uniform or shear current over a constant water depth is first validated with available analytical solutions and experimental data.
Comparisons among the experimental data, analytical solutions, and present numerical results show good agreements.
Then, regular waves propagating over a submerged parabolic obstacle with a following current are investigated.
Detailed discussions including those on the velocity and vorticity fields and the relation between free surface and vorticity are given.
