  7. Abstract:
  8. The purpose of this study is investigation of the effect of the porous medium permeability on heat transfer and pressure drop inside tube and compare the results with non-porous tube. In order to create porous medium in this research iron bullets with 2.93, 4.74 and 6.97 (mm) diameters has been used in test tube. Test tube made of copper with an inner diameter of 2 cm and has 1meter length. This experiment is done in steady state, transient and turbulent flow regime (2600< <12260) and also for constant heat flux boundary condition . The experimental results show that the values of heat transfer and pressure drop of porous pipe is always greater than non-porous pipe and these values will increase with respect to decreasing of permeability coefficient of porous medium and increasing of Reynolds number. Also, the highest heat transfer and pressure drop are measured at and which are permeability and Reynolds number respectively that increased heat transfer and pressure drop 8.84 and 833.56 respectively. In order to analyze the test design response surface methodology (RSM) method has been used to extract correlation relationships and optimize input parameters. The results of this experiment show that the effect of permeability coefficient porous medium on heat transfer and pressure drop is higher than Reynolds number and at and we have optimal amount of pressure drop and heat transfer with 50.78% available desirability
