| 摘 要： | 本文对底部加热的水平空气层的自然对流换热进行了可视化实验研究,采用实时全息干涉照相技术获得了温度场的激光干涉图及流场的烟可视化图象。实验结果表明,这种水平空气层自然对流换热是非稳态的,并且在空间上是三维的。

| Abstract: | Visualization experiments are performed for the natural convection of horizontal air layer heated from below. In experiments, the images of the temperature field of horizontal air layer heated from below are gained by using holographic interference measuring technology, and the images of flow fields for this problem are gained by using smoke visualization technology. The results of visualization experiment show that temperature and flow fields are un-steady and three dimensional in space for this natural convection of horizontal air layer heated from below. |
