摘要：

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. © 2019 Journal of Mechanical Engineering.
