EXPERIMENTAL INVESTIGATION OF A TWO DIMENSIONAL HEAT TRANSFER PERFORMANCE OF OPEN-CELL ALUMINUM FOAMS WITH THE GIS-BASED SUPPORT METHODOLOGY

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 o C;  X= 200 mm, Y= 10 mm; ΔT 30,2 = 40.78 o C). 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.
