摘要:
本文用马赫—曾德尔(Mach—Zehnder)光干涉仪研究了在大形状比(A=L/D=100)、不同壁面温度下矩形空间内空气层中的自然对流传热。显示和分析了从干涉图得到的温度分布,提供了端壁有空气渗入情况下的局部及平均传热关系。以层厚计的G_{rD}数范围1.64×10^3~2.46×10^5,研究结果与前人进行了比较。
Abstract:
This paper applies a Mach-Zehnder interferometer to the investigation of natural convection in an air layer enclosed in rectangular cavities with large Aspect Ratio of 100 at different temperature conditions. Visualization and analysis of the temperature distributions obtained from interferograms have been made. The local and the average heat transfer relations for the end walls with air penetrated are presented. The Grashof number specified by layer thickness ranges from 1.64×10~3 to 2×10~5. The results are compared with that of the previons investigators,
