Abstract
A simulation of a marine propeller was done to obtain the propeller’s open water characteristics using RANSE method with the approach of rotating reference frame. The effects of grid type, mesh density and turbulence models on simulation results were analyzed by comparing the results got from a four different cases representing combining turbulence models with grid types. The verification and validation of results were done by using the Potsdam propeller PPTC results. Eventually, choosing the grid type and the right turbulence model corresponding to each case was shown to obtain accurate results with minimum error from the experimental results. The results shows superiority of tetrahedral grid type with K-epsilon turbulent model in simulating the issued marine propeller performance.
