用热线测量旋流射流的优化处理方法

摘要

研究了单丝斜热线探针多方位旋转测量技术的数据后处理方法。针对 射流流场的速度特征 及单丝斜热线对垂直支杆来流的响应特性，提出了测量数据优化处理方法。结果表明， 优化的方法可以得到更精确的结果。%The aeronautic disturbance of hot-wire anemometry should be considered in turbu lent flow velocity measurements.The multi-position rotating methods with inclin ed single-wire are studied in this paper.In view of the velocity prof ile charac ters of the swirl jet and the response of the inclined single-wire probe perpen dic ular to the main flow,the optimized data process is introduced.The experimental results show that the optimized solution is more exact.
