摘要
介绍了热线、激光多普勒和粒子图像等3种测速仪的测量原理,装置性能和主要用途,比较了3种测速仪的优缺点。通过对比和分析得出热线测速仪适合熔喷流场的测量,激光多普勒测速仪和粒子图像测速仪适合纺黏流场的测量。
The measurement principle, equipment properties and main uses of HWA, LDV and PIV were introduced, the advantages and disadvantages of the veloeimeters were compared. Through comparison and analysis,it was coneluded that hotline veloeimeter suitable for melt-blown flow field measurement, while laster doppler veloeimeter and particle image veloeimeter suitable for spun-bonded flow field measurement.
