用七孔探针定量地测量空间流场是目前国内外在发展中的空间流场测量方法之一。南京航空学院于1983年在国内首次研制成七孔探针,研究出有实用价值的校准方法并较精确地进行了低速校准,实现了定量测量流动角高达80°的流动。1986年,使用IBM-PC机成功地开发了一套图形彩色显示软件,实现了空间流场定量彩色图形显示,把流场的速度绘成矢量图,压力值绘成等压力线图或等压力区图,形象地定量描绘出空间涡结构、涡系发展规律及
Quantitative measurement of the spatial flow field with the seven-hole probe is one of the methods for measuring the spatial flow field currently in development at home and abroad. Nanjing Aviation Institute in 1983, the first time in China developed a seven-hole probe, developed a calibration method of practical value and more accurate low-speed calibration, enabling the quantitative measurement of flow angle up to 80 ° of flow. In 1986, using IBM-PC successfully developed a set of graphical color display software to achieve a quantitative color flow space graphic display, the velocity of the flow field as a vector diagram, the pressure values such as pressure isogram or pressure Area map, image quantitatively depicts the spatial vortex structure, vortex system development law and
