Abstract

Turbulence level measurement is vital for the research on compressible fluid. Research on calibration method of constant temperature (CT) hot-wire anemometer is carried out. We build a calibration mathematical model for CT anemometer by combining the logarithmic function with the multiple regression technique, and conduct wind tunnel tests on turbulence level measurement to verify the model. Calibration tests are conducted with Mach number varying from 0.3 to 0.55, and data fitting is based on the mathematical model proposed. The results show that the correlation coefficient is R2=0.999 82 and the absolute deviation of velocity in average is u=0.18 m/s, basically meeting the accuracy requirements of CT anemometer calibration. The turbulence level is measured at Ma=0.55. The deviation of velocity measurement is 0.034%, and the turbulence level is Tu=0.14%. The results verify the feasibility of the application of CT anemometer in velocity measurement of the compressible fluid.
