摘要: 为深入理解液力变矩器这种典型旋转叶轮机械内部复杂三维流动现象,获取导轮叶片表面典型部位压力分布规律,提出一种定子叶片表面液体压力场测试方案,通过在导轮叶片压力面埋入微型动态压力传感器,对不同输入转速和速比工况下的导轮叶片表面典型部位压力进行试验测试并进行流场数值模拟对比。结果表明,测试数据与模拟结果高度吻合,较准确地描述了叶片表面压力场的变化趋势,叶片表面压力脉动频率与旋转叶轮转速及叶片数有关。这种压力测试方法不仅能对流场数值模拟进行有效性验证,同时也能为叶轮动态性能设计提供参考依据。

Abstract: In order to deeply understand the complex three-dimensional flow phenomenon in a rotating machinery such as a hydrodynamic torque converter and obtain the pressure distribution law of the typical sites of the stator blades surface, a testbench scheme of the fluid pressure field on the stator blade surface is proposed. The micro dynamic pressure sensors are adopted to measure pressure distribution of typical sites on the stator blade surface under different operation conditions of various input speeds and speed ratios. The test data are compared with the CFD numerical simulation of flow field. The results show that the test data are in good agreement with the simulation results. The variation trend of the pressure field on the blade surface is accurately described. The frequency of the pressure pulsation on the blade surface is related to the rotational speed of the impeller and the number of blades. This pressure field test not only validates the numerical simulation of flow field, but also provides a theoretical reference for the design of dynamic performance of rotating machinery.

Key words: computational fluid dynamic, hydrodynamic torque converter, pressure measurement, stator blades
