| Abstract: | Firstly, we state the surface overlap technique, and then introduce the basic principle of overlap grid and surface overlap processing method. On this basis, we do the resistance numerical simulation for one marine surveillance ship with appendages by using single phase level-set method and RANS equation. The flow field and free surface wave are analyzed, comparing with model test results, numerical calculation results are in good agreement with the test results, error can meet the engineering accuracy requirements, verifying the surface overlap technique is reliable which can be applied to resistance numerical simulation for ship with appendages. |
