摘要
五孔探针是测量复杂三维流场标量和矢量特性的常用手段。因其精度高,设备简单,成本低,对环境要求低等优点被广泛应用。由于其直接与气流接触,同时,实际测量要依赖于校准结果。因此结构设计和校准是探针应用中的重点。本文通过翻阅国内外探针的研究成果,比较全面的描述了目前国内外常用五孔探针的结构及校准技术(包括理论校准方法),简要讨论了国内五孔探针技术的发展前景。对五孔探针的使用和选择具有参考价值。
Five-hole pressure probe is common tool in the 3D flow field measurement. Due to several advantages, such as high accuracy, simple taeility, low cost and low requirement in environment, it is very popular in many applications. Since it is contact with flow directly and the real measurement should rely on calibration results. Therefore construction design and calibration are essential in probe application. This paper presents cun-ent construction and calibration of five-hole probe by reading and studying ＂abroad and domestic researches. The paper can provide guidance for five-hole probe application and selection.
