摘　　要：本文在三维船体贴体坐标系下 ,运用有限解析解法对控制方程进行离散 ,采用压力与速度耦合的改进的 SIMPLER计算方法结合标准的 k-ε方程湍流模式 ,数值求解三维 RANS方程 ,对作斜航运动的 Wigley船体的粘性绕流场进行了计算 ,并与他人结果进行了比较 ,验证了理论计算方法和数值离散技术的可行性和有效性。In the present paper, the 3D RANDS equations are solved on a three dimensional hull body fitted coordinate system by using the finite analytic method and standard k ε turbulent model with wall function, and a modilfied new SMIPLER algorithm is proposed to be used as an equal order pressure velocity coupling scheme. The three dimensional viscous flow around a Wigley ship model in oblique motion is computed. Part of the present calculation results are compared with the existing results obtained by experiments and those from other theoretical approaches.
