Abstract:

Based on the incompressible RANS equation, the KVLCC1 ship’s resistance field’s numerical simulation is carried out. In this paper, the bare hull (calm water resistance and wave resistance) and hull-propellerrudder models are studied and compared with the values of the Hydrostatic resistance test. In the hull-propeller-rudder system’s performance analysis, the body force method is used to replace the real propeller model. The new calculation domain is set for the hull-propeller-rudder system model and meshed again to obtain the highly reliable numerical simulation results. Finally, the calculation results are analyzed. The research results in this paper can provide technical support for the resistance of similar ship types.
