A three dimensional computational study of the thermo-hydraulic characteristic of the fin-tube heat-exchanger with the upward rectangular winglets vortex and the elliptical tube of various elliptical ratios are analyzed in the study. The ratios are b/a=1.0, b/a=0.333 and b/a=0.307. The numerical studies is performed with the Reynolds no (R e,) within the range of 500-3000.The temperature contour and streamline patterns were presented to explain the reason for the pressure drop and heat transfer and to analyze the flow in different arrangement. It is demonstrated that the upward rectangular winglets vortex and the elliptical tube design in case of lesser pressure loss and less separate flow which is preferred in the heat-exchanger application in order to save energy.
