摘要
通过热线流速计等实验手段 ,对空调用贯流风扇出口处紊流强度和速度脉动进行了实验研究 ,得出了贯流风扇出口处相对紊流强度的分布规律和速度脉动与贯流风扇扰动频率及流体噪声的关系。
The relative intensity of turbulence and velocity pulsation in exit of cross flow fan were studied by using hot-wire anemometer measurements. The existence of disturbance frequency was proved. The distribution regularity of turbulence relative intensity and relation between velocity pulsation and hydronoise were obtained.
