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.

当导电垂直壁在不同温度下分离两种流体时，热耦合自然对流系统就会发生。例如，在将房间内部与外部的内部分开或将流体容器放置在冰箱中时，发生这种配置。 改善建筑物的加热/冷却和通风，以及更有效的制冷系统，需要对这些流动有透彻的理解和预测能力。该项目将开发实验性，数值和分析工具来预测这些流量，并为大量流量参数（例如横跨墙壁的热传递）提供简单的缩放关系，这将在相关行业中立即使用。
