摘要
为研究跨声速轴流压气机叶片积垢形成机理,针对目前轴流压气机试验台为固定叶片,或仅为低转速转子试验台的现状,结合粒子图像测速(Particle Image Velocimetry,PIV)技术,根据跨声速转子NASA Rotor37的性能参数,设计了一种精确捕捉跨声速轴流压气机转子叶片通道内流场分布的试验台。该试验台由变频调速电机提供动力,进、出口段设置有压力与温度传感器,出口段还设置有流孔板和节流阀。检测数据通过工业控制计算机自动采集和处理,能实现轴流压气机转速、质量流量、进出口温度与压力的测量,通过结合PIV系统能对压气机转子叶片通道流场分布进行锁相测量。该试验台通用性强,也可用于跨声速轴流压气机内非定常流、旋涡、激波等复杂流动的研究。
Abstract：blade which was fixed or just the low speed rotor test rig, using Particle Image Velocimetry （Particle Image Velocimetry ,technology, and according to the peformance parameters of NASA Rotor37, it designed a transonic single stage axial compressor test rig to precisely capture the distribution of flow field in the blade passage. The test rig adopted frequency conversion motor to provide power, inlet and outlet section set pressure sensor and temperature sensor, and inlet also set a flow orifwe and throttle. Testing data was automatically collected and processed by industrial control computer, the test rig can measure axial compressor speed, mass flow, import and export temperature and pressure, and can measure compressor rotor blade passage flow field of phase lock by the PIV system This test rig is multifunctional, it can also be used for unsteady flow, vortex, shock wave and other complex flow study in transonic compressor.
