为了分析串列螺旋桨的水动力性能,本文运用计算流体动力学理论,结合雷诺时均RANS方程和相对运动参考坐标系对其三维定常粘性流动进行数值模拟。应用Fortran语言编制程序计算螺旋桨的型值点,并采用三次样条曲线拟合各点,建立串列桨三维模型。以某一串列螺旋桨作为研究对象,得到螺旋桨的推力系数、转矩系数以及流域内速度分布等水动力特性参数,并给出敞水性能曲线。计算结果与试验数据吻合较好,验证了数值方法的可行性和准确性。
In order to simulate numerically the tandem propeller hydrodynamics performance of steady viscous flow, the computational fluid dynamics (CFD) method based to the Reynolds-averaged navier-stokes (RANS) equation and the moving reference frame technique is used in the paper. A 3D model of tandem propeller is built according to the points of propeller were calculated by Fortran program and optimized by the method of NURBS. such as thrust coefficients, torque coefficients and the velocity distribution. The computed results agree well with the experimental data such as thrust coefficients, torque coefficients and the velocity distribution. It shows that the numerical method has good accuracy in the prediction of tandem propeller open-water performance.
