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= Tx, y-Ti) 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: ΔT10,2 < ΔT10,1 < ΔT20,2 < ΔT20,1 < ΔT30,2 < ΔT30,1 and the maximum performance was found at the 3rd situation where the data were (ΔT30,1=66.95 ºC; X= 200 mm, Y= 10 mm; ΔT30,2= 40.78 ºC). The empirical correlation of the capacity of non-dimensional performance for the 3rd situation can be expressed as follows (Formula Presented). 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.
