Design of Transonic Single Stage Axial Compressor Test Rig
For the study of transonic axial compressor blade fouling formation mechanism,in view of the present axial compressor test rig blade which was fixed or just the low speed rotor test rig,using Particle Image Velocimetry(Particle Image Velocimetry,technology,and according to the performance 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 orifice 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.
