| Abstract: | To predict the open water performance of a ship propeller under different pitches, the numerical simulation on open water performance of the standard propeller DTMB 4119 is performed. The comparison of computation results and test results of thrust coefficient and torque coefficient indicates that it is feasible to simulate viscous flow field of the propeller by solving RANS equations. The method is applied to predict the open water performance of a ship propeller, and the thrust factor, torque factor, surface pressure factor, and wake flow are simulated under different pitches. The open water performance of a ship propeller can be well analyzed by RANS method. |
