Simulation of turbulent flows over moving sinusoidal waves

In this study, turbulent flow over moving sinusoidal waves with different wave slope and wave speed is investigated by solving the Reynolds-averaged Navier-Stokes (RANS) equations using a commercial computational fluid dynamics (CFD) software package. The RANS models include the kappa-epsilon, kappa-omega, and Reynolds stress formulations. The results show that the imposed waves significantly influence the pressure and friction stress, and velocity distributions. The performance of the turbulence models was presented, and the effects of wave slope and wave speed were compared and discussed.
