The boundary condition slip-walls for the lower and higher walls of the micro-channel and orderly, as insulation and constant temperature is considered, respectively results show that the heat transfer increased with increasing Darcy number and the porous-medium film thickness. The consequences disclosed that the place of the porous-film has a substantial effect on heat transfer. The percentage changes observed for cases such the porous layer in the middle of the micro-channel, near the two upper and lower walls, near the upper wall, near the upper wall and in the form of a rib, along the length of the micro-channel with L /3 and L/5 is -14%, 2.25%, 5.46%, 55.53%, 70.5% and 86.27% for nusselt number compared to the porous layer-less state.}, keywords = {Micro-channel,Porous media,heat transfer,nano-fluid}, url = {https://www.ije.ir/article_115332.html}, eprint = {https://www.ije.ir/article_115332_26915c1f2ef9c56c956cbff717046bb4.pdf} }
