A flow around a square rod made of porous medium was investigated exploiting a flow visualization technique. A numerical simulation was also conducted using a general set of the modified Navier-Stokes equations proposed by Vafai and Tien. It is found that the fluids penetrating into the porous rod from the front face are diverted towards two inner side faces. They blow out from the side faces, modifying the external flow field around the rod.
