Material Selection for an Optimized Fin Geometry Through Longitudinal Perforations by Using Analytical Hierarchy Process

Fins are basic structures which can be easily added to many engineering designs to improve heat transfer from hot surfaces. The addition of a fin to a particular heated surface can significantly increase the cooling at no extra cost. In some cases, standard fin structures are required to be optimized due to drawbacks of the application such as limited space and mass. Accordingly, the determination of appropriate fin material has crucial importance. In this study, selection of fin material for an optimized fin geometry through longitudinal perforations is evaluated systematically by using common decision tool called Analytical Hierarchy Process (AHP). The success of using AHP technique is revealed by using common heat engineering materials. It has been shown that, no single option is present for material selection. As a conclusion, a standard decision procedure to determine appropriate fin material can be implemented and alternatives schemes can be investigated.
