© Emerald Group Publishing Limited 2015.Purpose - Natural convection with heat transfer in porous media has been subject of extensive study in engineering due to its numerous applications. A case of particular interest is the Bénard-type flow.The paper aims to discuss this issue. Design/methodology/approach - Based on the network simulation method in order to solve this problem, a numerical model is proposed. Findings - Nusselt-Rayleigh correlation is determined for a broad range of Rayleigh, the dimensionless number that influences the solution, above and below the threshold which separates the conduction and convection pure mechanisms. Originality/value - Based on the network simulation method.
