OPTIMIZATION OF A MICRO-CHANNEL STRUCTURE OF AN ELLIPTICAL LOUVER FIN

ABSTRACT
The influence of the louver fin's structure on the heat transfer performance of a parallel flow gas cooler is studied, and a 3-D model for an elliptical louver fin is simulated for analysis of the heat transfer and flow resistance characteristics of the fin. The micro-channel structure of the fin is optimized to give the best comprehensive performance evaluation by suitable choice of fin's thickness and the space between the adjacent louvers for given range of Reynolds number.
KEYWORDS
