TL;DR: In this article, the authors summarize the published articles in respect to porosity, permeability (K) and inertia coefficient (Cf) and effective thermal conductivity (keff) for porous media, also on the thermophysical properties of nanofluid and the studies on convection heat transfer in porous media with nanoparticles having dimensions of (1-100) nm.

TL;DR: In this article, the authors studied the transient free convection in a two-dimensional square cavity filled with a porous medium, and the results were obtained for the initial transient state up to the steady state, and for Rayleigh number values of 10 2 -10 4.

TL;DR: In this paper, the effects of the amplitude of the bottom wall temperature variation and the heat source length on the natural convection in the cavity are investigated for Rayleigh number range 20-500.

TL;DR: In this article, the Darcy model is used in the mathematical formulation for the porous layer and finite volume method is used to solve the dimensionless governing equations, and the results including the streamlines and isotherm patterns and the local and average Nusselt number for different values of the governing parameters.
