利用所研制的相关测试系统,借助高精度的热线风速仪作为标定设备,在标准风洞内进行了相关测量的实验研究,实现了利用过零极性相关法测量流体流速,并对测量结果进行了分析。 Based on the related test system developed, the hot air anemometer was used as the calibration equipment to carry out the experimental research on the related measurement in the standard wind tunnel. The measurement of the fluid velocity by the zero-crossing-polarity correlation method was realized and the measurement results were carried out Analysis.
