Numerical study of heat and momentum transport in horizontal convection at large Rayleigh numbers

在这个项目中，我们将研究数值水平对流系统，在这个系统中，热量完全通过单一的、顶部或底部的流体表面提供和释放。这种类型的热对流在许多地球物理和天体物理系统中以及在工程应用中无处不在。本项目的主要目的是全面研究水平对流中的对流热量和动量输送，并推广ShishkinaGrossmann，Lohse，GePhys等人的理论。莱特资源。43(2016)。直接数值模拟将在广泛的普朗特数和瑞利数范围内进行。这将使我们能够详细地研究高瑞利数水平对流中的流动结构，并验证理论预测的标度区域。

In this project we will investigate numerically horizontal convection systems, where heat is supplied and removed exclusively through a single, top or bottom, surface of a fluid layer.This type of thermal convection is omnipresent in many geophysical and astrophysical systems and in engineering applications. The main aim of this project is to study in a comprehensive way the convective heat and momentum transport in horizontal convection and to advance the theory from Shishkina, Grossmann, Lohse, Geophys. Res. Lett. 43 (2016). Direct numerical simulations will be conducted in a wide range of Prandtl numbers and Rayleigh numbers. This will allow us to investigate in detail the flow structures in high-Rayleigh-number horizontal convection and to verify the theoretically predicted scaling regimes.
