In this paper the fluid flow and heat transfer in a channel with hot solid block which is located inside a square porous block was carried out numerically. The lattice Boltzmann method with nine velocities, D2Q9 was employed in all numerical simulations. The effects of some parameters including ratio of the thermal conductivities of fluid and solid structure of porous media, and Darcy number on flow pattern and thermal field were investigated. The result shows that with increasing the thermal conductivity ratio and decreasing Darcy number, the fluid temperature will reduce.
