| Popis: | Numerical wave tanks rely on specific models to generate realistic wave condition, propagate accurately the waves in the domain, and absorb the reflected waves at the boundaries. In this paper, three wave modeling methods for two-phase CFD solvers are compared, including the Internal Wave Generator method, the Relaxation Zone method, and the Spectral Wave Explicit Navier Stokes Equations (SWENSE) method. The first two methods consist in generating and absorbing the waves in specific regions of the domain, while the third achieves a potential/viscous coupling in the entire domain. These methods, implemented either in OpenFOAM or in ISIS-CFD are compared by simulating a fixed Catenary Anchor Leg Mooring (CALM) buoy in regular waves. The simulation results are compared with available experimental data obtained by a model test in the Ocean Engineering Tank of Ecole Centrale de Nantes. The comparison shows the efficiency and the accuracy of these waves modeling methods. A problem related to the turbulence modeling in two-phase flow is also remarked. |
