Abstract: In this article,several typical modern flow measure techniques are introduced separately,which include hot wire Anemometry(HWA),Laser Doppler Anemometry(LDA),Phase Doppler Anemometry(PDA),Particle Image Velocimetry(PIV) and Plane Laser Induced Fluorescence(PLIF). Based on the introduction and analysis of the interior application status of these techniques,the importance of applying these techniques to measuring flow characteristic in impinging mixer are addressed. A new impinging stream device is also introduced,and the further study on the impinging stream is prospected.

Key words: hot wire anemometry(HWA), laser doppler anemometry(LDA), phase doppler anemometry(PDA), particle image velocimetry(PIV), plane laser induced fluorescence(PLIF), impinging stream
