In recent decades, the Lattice Boltzmann Method has received attention due to capabilities such as simple structure, simplicity of coding, explicitness, and many other reasons. As we know decreasing the size of the data processing microsystems significantly causes to increase in the thermal flux produced in these systems. So that the standard cooling systems such as air cooling do not have the ability to repel this high heat flux, the only way is using the high efficiency or better alternative methods. In the meantime, many experts have been suggested using microchannels with a porous media structure as a high-performance cooling system. Therefore, in this project, researches are done on a two-dimensional geometry in cartesian coordinate, the geometry in this research is a microchannel that is included a homogeneous porous media particles. To solve the temperature field, the D2Q9 method will be used and also for the velocity field D2Q9 approach will be used. In this study, the effect of using nanofluids and porous media particles to improve heat transfer and fluid flow in microchannel will be investigated.
