【 摘 要 】

Class 470 yacht attracts more and more attention at the World Championships. The hull hydrodynamics is important for winning the games. Hull draughts influence ship maneuverability, seakeeping, rapidity and stability. Numerical simulation by solving RANS equations is used to hull hydrodynamics with different draughts for the 470 Class yacht. Turbulence model is (SST) k-ω. The results show that wave resistance, viscous pressure resistance, friction resistance with the Froude number is different when the hull draught is different. According to the results about hull hydrodynamics with different draughts and the aerodynamics of the sail wing, the resistance performance of the hull is good when the hull draft for 470 Class yacht is within a relatively reasonable zone. This study on resistance performance of the hull provides a theoretical reference for coaches to talent selection of sailing athletes, weight distribution of athletes, estimate the sailing route and maneuverability of the sailing boat.
