Abstract

470 Sailing race requires effective cooperation between athletes to optimize hull position and correct heading. In order to understand the effect of hull on the maneuverability of rudder and the influence of rudder on the stability and rapidity of the hull at different ship speeds. Numerical 3D simulation and research on the viscous flow field of 470 Sailing based on Reynolds-averaged Navier-Stokes Equations. The results show that the rudder can reduce the wave making characteristics of hull, reduce energy loss and thus improving the hull's rapidity when the speed is greater than 6m/s, the effective area of rudder decrease and increases the stall angle, which reduces the manipulatable performance of the rudder to some extent. This study could quantify the performance of hull and rudder at different speeds. Moreover, this study might provide strategies for the athletes to effectively control the rudder and hull at different speeds.
