本文应用 Vintens ESPI、全息干涉及新发展的 Video 的全息干涉技术,研究了水平热管的自然对流现象。介绍了这三种技术的光学系统,和关于气体温度场的测量原理和测量结果。与热电偶所测温度值比较,结果相当一致。文中还就可能的测量误差作了定性分析。
In this paper, holographic interference technique of Vintens ESPI, holographic interference and the newly developed Video is used to study the natural convection of horizontal heat pipe. The optical systems for these three technologies are introduced, together with the measurement principle and measurement results of the gas temperature field. Measured with the thermocouple temperature values, the results are quite consistent. The article also made a qualitative analysis of the possible measurement error.
