Handheld Flow Field Test and Display Technology Based on 7-Hole Probe

为快速方便地获取流场信息,研究一种基于七孔探针的流场测试与显示技术。通过探针获取流场速度信息,由Optotrak系统获取探针的位置和姿态信息,进而通过数学工具的插值,将流场进行图形化显示,并利用该技术在风洞中开展测试实验。实验结果表明:该技术装置结构简单,使用灵活,可快速地获取流场信息,为流场的测试提供一种新的方法和思路。

In order to obtain flow field information quickly,a kind of technology based on 7-hole probe is designed.It obtains the velocity of the flow field by the probe,and gets the position and attitude of the probe by the Optotrak system, and then the flow field can be graphically displayed by the interpolation of the mathematical tool.The experiment was carried out in wind tunnel.The result shows the device is simple in structure and flexible in use.It can acquire flow field information,and it provides a new method and thought for flow field test.
