Title: Numerical modeling of wave–current forces acting on horizontal cylinder of marine structures by VOF method
Abstract: In this study, a numerical model is applied to study the interaction of solitary wave and uniform current and their forces acting on a horizontal cylinder near the free surface. The model is based on the Reynolds-averaged Navier–Stokes (RANS) equations, and the k−ε turbulent model is used for the closure of the RANS equations. The free surface locations in the model are represented by the Volume of Fluid (VOF) method. The model is satisfactorily tested against both the experimental data of flow forces acting on a horizontal cylinder and the analytical solution of solitary wave. The validated model was applied to simulate solitary wave, uniform current, and their interaction with the horizontal cylinder in coastal structures. The vortex contours around the cylinder are investigated for analysis of wave–current effects on forces acting on horizontal cylinders. Modeling results indicate that forces from combined wave and current action are larger than simple summations of wave force and current force.
