Özet
In this study, performances (Delta T= T-x,T-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: Delta T-10,T-2 < Delta T-10,T-1 < Delta T-20,T-2 < Delta T-20,T-1 < Delta T-30,T-2 < Delta T-30,T-1 and the maximum performance was found at the 3rd situation where the data were (Delta T-30,T-1= 66.95 degrees C; X= 200 mm, Y= 10 mm; Delta T-30,T-2= 40.78 degrees C). The empirical correlation of the capacity of non-dimensional performance for the 3rd situation can be expressed as follows Delta T-30,T-1 (and 2) /(Delta T-30,T-1 and 2)(max) = 6.10(-8) X-4 - 2.10(-5) X-3 + 0.001X(2) - 0.082X + 1.459. 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.
