Abstract: | Cavitation is a highly destructive phenomenon that significantly disrupts the performance of propellers and control surfaces in the maritime industry. Hence, the prediction of forces developed during cavitation, through various numerical techniques, is imperative for the design and operation of maritime vessels. RANS turbulence models have proven to be the most computationally viable option for such a fast-paced industry. The work presented here analyses and compares several of these well-established models, including the SST k-ω and k-ε RNG models modified to account for compressibility effects. This paper aims to provide insight into the influence of timestep, mesh resolution and turbulence model on the hydrodynamic forces acting on a 2D cavitating hydrofoil, so as to facilitate future simulations. |
