Numerical investigation on a heat transfer model for high Biot number porous media

Shota Kurishima, Yoshihiko Sano, Fujio Kuwahara

Abstract

This study focused on heat transfer in a porous media with high Biot number. Introducing the nunsteady volume averaged Nusselt number, temperature distribution in a porous media with high Biot number was estimated by an analysis of non-thermal equilibrium macroscopic energy equations. Comparison of temperature distributions between the presented analysis and the direct numerical simulation revealed that the presented analysis is reasonable to treat with heat transfer in a porous media with high Biot number.
