已经进行了实验来研究侧面照射的垂直矩形外壳中自然对流运动的内部辐射加热速率。马赫-曾德干涉仪用于确定温度场，并采用荧光染料注入技术来说明以水为工作流体的流动结构。开发了一个理论模型来预测热辐射的吸收和随后的浮力驱动流。基于辐射通量发散的光谱计算的预测与实验数据非常吻合。
Experiments have been performed to study the rate of internal radiative heating on the natural convective motion in a vertical rectangular enclosure irradiated for the side. A Mach-Zehnder interferometer has been used to determine the temperature field, and a fluorescing dye injection technique was employed to illustrate the flow structure with water as the working fluid. A theoretical model is developed for predicting the absorption of thermal radiation and the subsequent buoyancy-driven flow. Predictions based on spectral calculations for the radiation flux divergence agree well with the experimental data.
