The author proposes a new method to estimate the heat transfer between fluid gas and solid material in a porous medium. In the first stage, the local Nusselt numbers on the heated wall of a flow passage with a porous medium are numerically obtained in advance for the parameter Ha including the volumetric heat transfer coefficient, hv between the fluid and the solid material in a porous medium. In the second stage, the experimental Nusselt numbers on the heated wall are obtained by measuring wall temperatures and heat flux. The volumetric heat transfer coefficient, hv, is evaluated by comparing experimental Nusselt numbers with numerical ones. This method also gives the longitudinal characteristics of the heat transfer in a porous medium.
