Large Scale Natural Convection Boundary Layers with Non-Boussinesq Effects

本提案旨在了解和预测两种情况下湍流自然对流的换热，一种是在非常大的环境尺度下，如南极冰盖融化，另一种是在太阳热电厂和工业过程中发生的涉及非常大温差的对流。这些自然对流流动模式很难直接研究，但通过大规模数值模拟和创新实验来关注湍流流动的基本动力学，该项目有望开发出更好的分析和计算模型，这将巩固在

This proposal aims to understand and predict heat transfer by turbulent natural convection in two scenarios, firstly at very large environmental scales, such as occur on melting Antarctic ice sheets, and secondly convection involving very large temperature differences such as occur in solar thermal power plants and industrial processes. These natural convection flow regimes are incredibly difficult to investigate directly but by focusing on the fundamental dynamics of the turbulent flows using large scale numerical simulations and innovative experiments, the project is expected to develop better analytical and computational models which will underpin improvements in global ocean models and improve energy efficiency.
