摘要

部分多孔介质中的三维自然对流。研究了非平衡状态下多孔介质中的传递和流动。采用Darcy-Brinkman模型。采用双方程模型分别考虑了局部流体温度和固体温度。采用基于有限体积法的数值计算方法，即全多重网格技术。我们发现了导热系数对流动和传热的影响。

Study of transfer and flow in porous media in nonequilibrium

3D Natural convection in partially porous media. The Study focused on transfers and flow in porous media in nonequilibrium. Darcy-Brinkman model's is adopted. Moreover the two-equation model is used to separately account for the local fluid and solid temperatures. A numerical method based on the finite volume method a full multigrid technique is employed. We find the impact of the conductivities ratio on the flow and the heat transfer.
