Abstract

This study attempts to calculate the optimal geometry of convective-radiating radial of ICEs fin arrays using entropy generation method. The analysis is conducted to achieve the balance between entropy generation due to heat transfer and entropy generation due to fluid friction. In designing of the thermal system, it is important to minimize thermal irreversibilites, because the optimal geometry found while the entropy generation rate is minimized. In this study, the entropy generation minimization (EGM) technique based on fin thickness is applied to study the thermodynamic irreversibility caused by heat transfer and fluid irreversibility in radiating convective radial fin arrays. In addition, the cost parameters of fin optimum thickness is also considered and presented. The entropy generation is found to be strongly influenced by emissivity of fin material surface and increasing the cross flow fluid velocity will enhance the heat transfer rate that will reduce the heat transfer irreversibility.
