In this study, performances (ΔT= T_x,y- T_i) of open cell aluminum foams are investigated experimentally for three different situations with GIS (Geographical Information System) based support methodology. In the 1st situation; the conditions were 10 PPI, u=1 and 2 m/s, X=0-200 mm, Y=0-100 mm. In the 2nd situation; 20 PPI, u=1 and 2 m/s, X=0-200 mm, Y=0-100 mm. As in the 3rd situation; 30 PPI, u=1 and 2 m/s, X=0-200 mm, Y=0-100 mm. When the maximum performances of the three situations were compared, the following sequence appeared: ΔT_10,2 < ΔT_10,1 <  ΔT_20,2 <  ΔT_20,1 < ΔT_30,2 < ΔT_30,1 and the maximum performance was found at the 3rd situation where the data were (ΔT_30,1=66.95 ^oC;  X= 200 mm, Y= 10 mm; ΔT_30,2= 40.78 ^oC). The empirical correlation of the capacity of non-dimensional performance for the 3rd situation can be expressed as follows . Experimental results indicate that the performance depends on porosity density, the magnitude of the air velocity on the test region and the X and Y distances.
