Heat transfer between solids and gases plays an important role in various fields of engineering. In this study, we perform three-dimensional unsteady conjugate heat transfer numerical simulations of solids and fluids in a rectangular computational domain by arranging columns of cylinders parallel to the flow direction. Air is used as the fluid and ceria is used as the solid. The Reynolds number is calculated in the range of laminar flow. The heat transfer coefficient, Nusselt number, friction coefficient are calculated from the solid and fluid temperatures and the pressure drop between inlet and outlet, and the heat transfer characteristics are evaluated and applied to porous flow.
