Numerical simulation of traort phenomena in porous media parameters affecting metal Foam is the solid material with call structure of pore, which is recognize as “ spong”. High porouse, low pressure drope, highe thermal coefficient, and germ transition coefficient are example of foam specifications. On the other hand, physical and chemical specifications of fomas, have resulted in acknowledgeing foams as one of the main elements in desining and producing thermal transformation and catalistic materials. The porouse of presnt study is to investigate the fluide flow of thermal transfer in relation to air current with 500 K of aluminium foams( with variouse porouse percentage of 76-96 and variouse diameter of 100-500 micrometere) with 300 K. Since one of the important terms in thermal transfer is the fliude flow and geometrical parameters investigating the fluide flow affecting the fliude flow and geometrical parameres on thermal transfer was determined. For this purpose, in order to check the effect of geometrical parameters on fluide flow, two procedures were applied. In the first one, real geometry of fome was used in a way that foams with varouse porouse perecentage and Computational Fluide Dynamic method, the fluide flow with entering speeds of 1-8 m\\s was resembled. The results of thid study show that applying of real geometry is an appropriate method to chek the effect the pressure drop, since formula was presented ( ? P/L= ?v + ?v 2 ) of calculated and time of calculations. Hence, in second method simpler geometry wad made wihe Ansyse Work Bench software and geometrical parameters were taken in Source terms equtions using the equation of first methpde. The results of second methods show sensible decreased in volume and time of calculations. Forther, first method made it in possible to study extermal thermal transfer in foams. Therefore, mathematical reasonable formula was presented for alterations of Nuselt number according to Reynolds and strauctual parameter of foam Nu=0.302 Re 0.496 ((1-?)/?)) -0.519 (dp/dt) -8.22 .Thus, mathematical formulas foraverage of thermal transfer coefficient was presntde ased On speed ( h ave =C+?v+Bv 2 ) .Large amount of calculation of first method sensibly decreated by applying second method and thermal transfer coefficient equation obtained from first method. Forthrmore results obtained from second method have an ideal accuracy in anticipation of the thermal transfer in comparition with the first method. Therefore neglect of the complexity of foam geometry and its difficulties, with finding mentioned mathematical models, it could be possible to interesting and forcast their act in transferring the heat and fluide flow in real scale with less calculating size.
