摘要

摘要: 尺度效应问题是准确预报泵喷推进器水动力性能的关键, 文中通过求解雷诺平均Navier-Stokes方程(RANS), 对模型尺度和实尺度的泵喷推进器敞水性能进行数值仿真, 分析尺度效应引起的水动力差异。分析结果表明, 推进器各部件水动力均存在尺度效应, 其中导管的尺度效应最为显著, 而转子的尺度效应对推进器总体水动力的影响最大。

Abstract: Scale effects are important in accurately predicting the hydrodynamic performance of pump-jet propulsors. By solving the Reynolds-averaged Navier-Stokes equation, the open-water performances of model-scale pump-jet propulsors and full-scale pump-jet propulsors are simulated, and the hydrodynamic difference caused by scale effect is analyzed. It is discovered that the differences between model- and full-scale hydrodynamic performances are mainly attributable to the rotor furthermore, the scale effect is reflected in the hydrodynamic performance of each component of the propulsor, i.e., the scale effect of the duct is the most significant, whereas that of the rotor contributed the most to the overall hydrodynamic performance of the propulsor.
