空调用贯流风扇出口处紊流的研究

A Study on Turbulence in Exit of Cross Flow Fan

通过热线流速计等实验手段，对贯流风扇出口处紊流的相对紊流强度和速度脉动进行研究，得出了贯流风扇出口处相对索流强度的分布规律和速度脉动与贯流风扇扰动频率及扰动噪声的关系．

The relative intensity of turbulence and velocity pulsation in exity of cross flow fan were studied byusing hot-wire anemometer measurements. The existence of disturbance frequency was proved.The distributionregularity of turbulence relative intensity and relation between velocity pulsation and disturbance noise were obtained.
