| Abstract: | A numerical model of podded propulsor has been established,and the moving mesh is successfully applied to simulate the influence of running propeller.The open water performance characteristic of podded propulsor in unsteady viscous flow is numerically predicted,and the computed results are compared with the model test results,and the maximal difference of KT is about 2.9%,KQ is about 0.8%.It shows that the prediction technique developed in this paper is feasible.Further more some significant hydrodynamic ph... |
