Numerical simulation of propeller-hull interaction and determination of the effective wake field using a hybrid RANS-BEM approach In this study propeller-hull interaction is investigated numerically using a combination of a steady viscous CFD method (RANS) for the ship flow and an unsteady potential-flow method (BEM) for the propeller loading. This approach allows for interaction between hull and propeller with a significantly reduced computational effort compared to a full RANS approach. In addition, the RANS-BEM coupling provides the propeller designer with an effective wake field. RANS-BEM results for self-propulsion are obtained with two different RANS solvers. The computations show a prediction of propeller rotation rate and thrust within 2 to 3% of the experimental values.
