PERFORMANCE ANALYSIS AND OPTIMIZATION OF RECTANGULAR FIN ARRAYS USED IN PLATE-FIN HEAT EXCHANGERS

ABSTRACT
This paper deals with longitudinal rectangular fin arrays used in plate-fin heat exchangers. The temperature distribution and rate of heat transfer were obtained using 1-D and 2-D solutions. The ranges of independent parameters within which the 1-D solution was within 1% from the 2-D solution were determined. Simple analytical solutions were determined for the rate of heat transfer, fin effectiveness, and augmentation factor. The aspect ratio at which the rate of heat transfer reached a maximum was determined, as well as the corresponding effectiveness and augmentation factor.
KEYWORDS
