Abstract
In this study the effects of solid block location inside a porous block over heat transfer and fluid flow was investigated numerically. The two dimensional lattice Boltzmann method was applied for all numerical simulations. The fluid flow in the porous media was simulated by Brinkman-Forchheimer model. The results show that the flow behaviour and heat transfer are sensitive to the variation of the solid block location. It is illustrated that an increase in contact surface between solid block and porous block would increase the heat transfer. The maximum heat transfer occurs for solid block located in the centre of the porous block.
