通过激光幕及激光多普勒流速计 (LDV)等先进实验手段 ,对目前家用、车用小型空调中所使用的贯流风扇内部流场进行了可视化及流速分布研究 ,得出了有无热交换器及叶轮叶片倾角变化时贯流风扇内部流动变化的规律
By means of laser curtain and laser Doppler velocimetry (LDV) and other advanced experimental methods, the internal flow field of the cross-flow fan used in the household and car air-conditioners was visualized and the velocity distribution was studied. The regularity of the internal flow of the cross flow fan when the inclination of the impeller and the blade change
