摘要
Based on a body-force propeller model, the viscous self-propulsion flow field with free surfaces of model-scaled KRISO container ship KCS at ship point is numerically simulated with general CFD code FLUENT 12.0.16. The computation method of self-propulsion is validated by comprehensive comparison between computational results and experimental data. The mesh used in this paper is completely structured hexahedral cells and the comparison on flow details between computed results and experimental data is good, so the 330 000 cell mesh is also proved as high effective. Both the model ship towed test and self propelled test at ship point in still water are numerically simulated. And for the self-propulsion computation, either case with or without considering torque is computed. The results show that considering torque is favorable to improve the computation accuracy and capture the flow features, but with additional computational expense. ©, 2015, China Ship Scientific Research Center.
