Turbulence level is important in high speed wind tunnel experiments.Research on measurement techniques for turbulence level in compressible fluid is carried out to satisfy the need of tests with high accuracy in high speed wind tunnel.Based on the law of heat convection,response function of constant temperature hot-wire anemometer is derived in detail.Sensitivities of mass flux and total temperature are obtained,and the algorithm for the turbulence level in compressible fluid is built.Turbulence level measu...
