摘    要: 热线风速计和其它接触式测量方法比较,具有探针对流场干扰小,空时分辨力高,频响快等优点。它和激光风速计(非接触式)一起,已成为当前研究流动微观机理的主要测试技术。但它的应用范围却受测试环境洁净度的限制。当然,热线应尽量用于洁净的环境,但在某些场合很难保证流场中没有轻微的污染,这就引入了热线测量的污染误差——利用热线预校

Abstract:This paper presents a method of calibration with actual flow fields to decrease the influences of oil vapor mixing with dust on the measurement result,and to extend application of hotwire anemometer.Using this method,the measurement error due to contamination can ba controled within a acceptable range, as the source of contamination is near steady. A demostration of two-dimensional flow mesurements is given.
Keywords:hot wire anemomenters  measurement errors  interpolation
