摘　　要：对壁面动态压力传感器阵列测试技术进行了研究,并将该技术应用于某离心压气机转子叶尖的动态流场测试中,获取了大量的动态流场测试数据。采用锁相技术和线性插值方法对测试数据进行了处理和分析,并采用数据可视化技术将动态数据转化成压力分布云图,从云图中可以清楚看出离心压气机不同工作状态下转子叶尖的压力变化,有助于分析转子叶尖处泄漏流、前缘溢流以及泄漏流和分流叶片前缘的相互作用。转子叶尖流场测试及可视化分析结果可以为压气机性能验证和数值模拟方法的修正提供重要的技术支撑。The measurement technology of wall dynamic pressure sensor array is studied and applied to dynamic flow field measurement for rotor tip of a centrifugal compressor,and a large amount of dynamic flow field test data is acquired.The test data is processed and analyzed by phase lock technology and linear interpolation,and is changed to pressure distribution cloud map by using data visualization technology,the pressure variation of rotor tip on different operative mode can be distinguished clearly.The pressure cloud map can be helpful for the analysis of leakage flow and leading edge overflow and the interaction of leakage flow and shunt blade leading edge.The above analysis results can provide important technical support for the compressor performance verification and modification of simulation methods.
