The flow and heat transfer of fluids at supercritical pressure in porous media has attracted much attention due to its extensive applications, such as supercritical water-cooled nuclear reactor, CO2 gas cooled reactor, transpiration cooling and supercritical CO2 solar thermal power generation system. There are mainly two theories to describe convection heat transfer in porous media, i.e., the local thermal equilibrium model (LTE) and the local thermal non-equilibrium model (LTNE). Compared with LTE model, the LTNE model is a more detailed model that uses two energy equations to describe heat transport in the solid and fluid. The internal heat transfer coefficient is a key parameter for LTNE model which has been studied thoroughly and many correlations have been proposed.
