The heat transfer and pressure drop characteristics of plate-fin and tube heat exchanger is analyzed by using computational
modeling. The parameters which are considered in this analysis are space between the two fins, length of the fin and tube ellipticity.
The governing equations of continuity, momentum and energy are solved using the commercially available FLUENT software. Seven
different cases are considered for heat transfer and pressure drop analysis. The main findings are related to the spacing between
the fins, which is critical in terms of pressure drop. The tube ellipticity provides an increase in heat transfer coefficient and reduces
in pressure drop.
