Thermally coupled natural convection systems occur when a conducting vertical wall separates two fluids at different temperatures. Such configurations occur, for example, at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator. Improved building heating/cooling and ventilation, and more efficient refrigeration systems, require a thorough understanding and predictive capability for these flows. This project will develop experimental, numerical and analytic tools to predict these flows and provide simple scaling relations for bulk flow parameters such as the heat transfer across the wall, which will be of immediate use in the associated industries.

热耦合自然对流系统发生时，传导垂直壁分离两种流体在不同的温度。这种配置例如出现在将房间的内部与外部分开的窗户处，或者当流体的容器被放置在冰箱中时。 改善建筑物的供暖/制冷和通风以及更高效的制冷系统，需要对这些流动有全面的了解和预测能力。该项目将开发实验，数值和分析工具来预测这些流动，并为整体流动参数提供简单的比例关系，例如壁面传热，这将立即用于相关行业。
