测量温度脉动的一个改进方法

An Improved Method for Measuring Temperature Fluctuations

本文描述了温度脉动诊断的冷线方法。首先，讨论了冷线的响应方程；然后，通过冷线的实验校准，定量确定冷线测温系统的动态响应关系。作为冷线诊断方法的应用，对热混合层的脉动温度结构实施了测量，所得实验结果令人满意。

AbstractThe coldwire method for the measurements of the temperature fluctuations is described in this paper. The response equation on cold wire is discussed, then the relationship of Voltage output of coldwire system to the instantaneous fluid temperature is given by calibrating experiments. As application to the method, the temperature fluctuation structure of the thermal mixing layer is measured, These results are Satisfactory.
