| Abstract: | The artificial compressible approach was used to simulate the viscous flow around the DTMB P4119 propeller.The hydrodynamics parameters such as the thrust coefficient and torque coefficient were obtained.The dependence characteristics of grid and the adaptability of turbulent model were analyzed.Compared with the experimental results,the numerical results indicate the good agreement.It shows that the numerical approach is correct and this program can be used to predict the flow around the propeller. |
