The lattice boltzmann simulation of the heat transfer and fluid flow in a heat exchanger filled with
porous mediume was investigated using Lattice Boltzmann method. The problem consists of
square cavity with inlet and outlet thermally insulated ports and three hot fins with constant
temperature. The Brinkman-Forchheimer equation was used to simulate the porous domain. The
effect of porosity on heat transfer from the fins surfaces was studied at different Reynolds. By
decreasing of porosity, the heat transfer rate increases and the domain bulk temperature of the fluid
increases at lower time for different Reynolds numbers.
