Unsteady Natural Convention in a Porous Layer Heated from the Side

本工作探讨了瞬变机制的基本原理， 二维多孔介质自然对流 等温垂直和绝缘水平壁。 相关内部 时间尺度被确定为支配 流体饱和多孔层来验证该尺度的有效性 分析. 通过数值实验计算了热辐射 在文献中没有记录的那些稳定状态下的转移速率。 所有的工程传热相关性将被更新。

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.
