| 摘 要： | 本文提出一种改进的双斜丝测量三维平均、紊流流场方法。该方法的特点是根据热丝的方向特性确定方向系数k和h,无需在每一测点处先测出气流偏角,然后在偏角方位上进行测量,对流向直角区的三维平均、紊流流场测量结果表明,该方法简便而有效。

| Abstract: | A method to improve the measurement of three-dimensional mean and turbulent flow field with a double slanted hot-wire probe is presented. A prominent feature of the method is that the coefficients of direction t and h are determined according to the directional characterisitics of the wires. Therefore, there is no need to measure the flow direction at each measuring point prior to the velocity measurement along this predetermined direction. |
