【摘要】 以Ｃｈａｐｍａｎ和山崎的方法为基础，计算了作回转运动三维物体的横向力．为了探讨粘性对船舶操纵性水动力的影响，通过在物面上叠加平板湍流边界层排挤厚度，并以此作为新的物面边界，按照山崎方法进行了计算，给出了平板及Ｗｉｇｌｅｙ船型的计算结果，并与试验值作了比较更多还原

【Abstract】 Based on the method proposed by Chapman and Yamasaki, this paper calculates the lateral hydrodynamic forces acting on the three dimensional body in circular motion. The new model, that the plate vortex boundary layer displacement thickness is added on the body surface to simulate the real body surface boundary conditions, is proposed to study the viscosity effect for hydrodynamic forces of ship maneuverability. The comparisions between the calculated results of a flat plate and a Wigley model and the experimental ones verify the validity of the new model and the numerical method.更多还原
