Determination of Computational Domain for a Marine Propeller Geometry By Using Numerical Method

In this research, simulation of a marine propeller at 3-D geometry by using the commercial software of ANSYS-FLUENT was presented. In this study a fluid dynamic analysis for two models namely, B-Series and standard model 3686 was conducted.Numerical results with considered turbulence models were found to be in acceptable agreement with the experimental results. In this paper, performance of the propeller was investigated at different range of advance coefficient (J) by considering KT, Kq and η coefficients. Thrust and Torque coefficients were estimated and found to be in good agreement with the experimental results. In order to find the optimum domain, twenty computational domains were examined.
