摘　　要：直接用Euler/N-S方程求解水翼绕流的计算和设计问题,是目前这一领域研究的热点.在大型通用CFD商业软件FLUENT平台下,利用有限体积法和RNG湍流模型直接求解RANS方程对敞水舵流场进行了数值模拟,并计算了敞水舵水动力性能.利用SIMPLE算法求解,采用了二次迎风格式离散动量方程和离散湍流能量方程,所得结果和试验数据、实际情况进行比较,吻合性比较好,对于敞水舵的水动力性能研究和设计具有一定的参考价值.Straight use of the Euler/N-S equation to solve calculation and design problems of flow around the hydrofoil is a hotspot presently in this field. Under the platform of FLUENT, the RANS equation is directly solved by the finite volume method and RNG model to simulate the flow fieM of rudder, and computes its flow characteristics .The SIMPLE algorithm is used to solve equation with QUICK to discrete momentum equation and turbulent equation. Compared the calculation result with experimental data and actually nature, the result is reasonable and has some reference value to the research and design of rudder hydrodynamic.
