Purpose
– The purpose of this paper is to improve the volume-averaged models for free convection flow in porous media.

Design/methodology/approach
– A pore scale simulation is conducted against which an independent volume-averaged solver is fine-tuned.

Findings
– Micro and macro scale results can merge if proper choice of local thermal non-equilibrium and thermal dispersion models are selected. This depends on the range of Ra values investigated.

Originality/value
– This is the first time a work like this is published in the literature.
