以KCS船和KP505桨为对象,按照一定缩尺比完成三维模型建立、网格划分、边界条件设置并进行流场求解,将数值计算结果与已有试验结果对比,验证数值计算的准确性。按照已通过验证的数值计算方案对该KCS船完成不同盘面比螺旋桨下自航计算,结果表明在不同盘面比螺旋桨作用下船体阻力变化不显著,推力减额变化不显著,但总推进效率随着桨盘面比增大呈减小趋势。
Taking KCS ship and KP505 propeller as objects, complete the three-dimensional model establishment, mesh division, boundary condition setting and flow field solution according to a certain scale ratio. The numerical calculation results are compared with the existing test results to verify the accuracy of the numerical calculations. According to the verified numerical calculation scheme, the self-propelled calculation of the KCS ship with different disc ratio propellers was completed. The results showed that the hull resistance and thrust deduction did not change significantly under the action of different disc ratio propellers, but the total propulsion efficiency increased with The increase of the paddle-to-disk surface ratio shows a decreasing trend.
