摘要
用一台一维激光测速仪和一台二维激光测速仪组合成一套三维激光测速系统。用它测量了一个小风扇转子内的周期性流场 。
A stacked three dimensional Laser Doppler Anemometer(LDA)system has been developed on the basis of a one demensional and a two demensional LDA systems.This system was successfully used in the measurement of the rotational flow field inside a small axial fan rotor.The measurements reveal rich and complex flow structures near the blade tip region,in particular fine helical vortex structures are obtained,which prove the system a useful tool in turbomachinery flow measurement.
