Using Lattice Boltzmann Method to Investigate the Effects of Porous Media on Heat Transfer from Solid Block inside a Channel

A numerical investigation of forced convection in a channel with hot solid block inside a square porous blockmounted on a bottom wall was carried out. the lattice boltzmann method was applied for numerical simulations.the fluid flow in the porous media was simulated by brinkman-forchheimer model. the effects of parameterssuch as porosity and thermal conductivity ratio over flow pattern and thermal field were investigated. in thispaper the effects of mentioned parameters were discussed in detail. the result show with increasing the thermalconductivity ratio and porosity the fluid temperature will reduce.
