Abstract
Three-dimensional steady RANS computations simulate the flow around a conventional propeller operating in open water conditions. Turbulence is modeled by the shear stress transport SST k-ω model. The influence of the turbulence model is investigated using the realizable k-ε model in combination with enhanced-wall treatment as an alternative. Computed forces and velocity distributions downstream the propeller are compared with the experimental data obtained from open water tests and PIV measurements for the design advance number J. The thrust and torque coefficients arc compared for several advance numbers. The SST k-ω model performs well in predicting the performance of the propeller and the main characteristics of the propeller flow.
