Outline of Final Research Achievements |
Aluminum fabrics have been made from aluminum fibers in order to create new elements for heat transfer enhancement. Heat transfer experiment and pressure drop measurement have been done for the channel flow with corrugated aluminum fabric fins to investigate their performance. It was found that the average heat transfer coefficient caused by the insertion of the corrugated aluminum fabric fins attained 14 times higher value than that of no-insertion case. Also it was found that the pumping power required by the insertion of those fins showed smaller than those of fiber layers used previously, therefore, these new elements suggested to be used for wider range of heat transfer applications. As for the pressure loss decrease, the use of the bypass flow turned to be undesirable due to the severe decrease in heat transfer, however, shortening the porous body distance showed possibility to decrease the pressure loss maintaining high heat transfer enhancement.
