Numerical simulation of Nusselt-Rayleigh correlation in Bénard cells. A solution based on the network simulation method

Abstract

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.
