Unsteady Natural Convention in a Porous Layer Heated from the Side

这项工作探讨了在等温垂直和绝热水平墙壁之间的二维多孔介质中瞬态自然对流机制的基本原理。确定了控制流体饱和多孔层瞬态演化的相关内部时间尺度，验证了尺度分析的有效性。数值实验进行了计算传热率在那些稳态没有记录在文献中。所有的工程传热相关将被更新。

This work explores the fundamentals of the mechanism of transient natural convection in a two-dimensional porous medium confined between isothermal vertical and insulated horizontal walls. Relevant internal time scales are determined governing the transient evolution of the fluid-saturated porous layer to verify the validity of the scale analysis. Numerical experiments are performed to calculate the heat transfer rate in those steady states not documented in the literature. All of the engineering heat transfer correlation will be updated.
