The paper aims to study and evaluate the porous flow to determine the effect of these media on the behaviour of the heat exchanger. The digital method (CFD) was used to achieve this goal. The simulated procedure was using ANSYS software. The obtained results show that there is a great tendency to add porous medium to heat exchangers to increase heat transfer efficiency. This case was studied by pressure, velocity, and wall shear stress of heat exchangers. Also, when a porous material was placed in the pipe, the pressure values were affected, the pressure values differed along the length of the pipe, and its value was observed to decrease through the porous medium, the reason for this is that the wall of the porous area resists the flow, which works to reduce the liquid near the wall and from it, the force acting on it decreases. As the number of pores increases, the pressure value decreases. The velocity decreases through the porous media, this is due to the nature of the pores as they act as an obstacle in front of the liquid particles and collide with them. This collision leads to a loss of some momentum and the speed decreases due to the stability of the volume. Finally, the pressure gradients increase due to the porous media during the heat exchange. There will be seepage from the pipe if a pressure dispenser is placed or pressure relief is used.
