摘　　要：介绍了基于求解雷诺平均纳维-斯托克斯(RANS)方程的分区网格船舶操纵粘性流求解器,以及应用该求解器计算船舶操纵相关的粘性流动与水动力的研究工作.计算了舵的粘性流场和水动力,所预报的舵升力曲线和阻力曲线在舵角未达到失速角前,与现有的试验和计算结果符合良好,所预报的舵失速角稍偏小.还计算了6∶1椭球体和Wigley船体做大角度定常斜航运动时的3维粘性流场及水动力,正确地模拟这种以层流/湍流分离流为主的复杂粘性流动,从而检验和验证了该求解器精确模拟粘性分离流动和计算水动力的能力.Presented a multi-block incompressible viscous flow solver for the numerical simulation of the ship maneuvering flows and calculation of the hydrodynamic forces. The solver was applied to compute the hydrodynamic forces acting on a rudder and predict the stall angle. The results agreed well with the experimental ones. The computations were also performed for a 6：1 prolate sphere and a ship maneuvered at large incidence （yaw） angles and were in good agreement with the available experimental data and numerical resuits, showing that the solver is capable of predicting the hydrodynamic forces exactly.
