Abstract
The air side thermal performance of wavy fins with rectangular winglets are studied using experimental and numerical methods. The following parameters are selected for investigation: the attack angle, placed location, span and length of the rectangular winglet. The results show that all parameters affect the thermal performance of the air side. The best configurations of the winglet that provide the maximum j/f(1/3) for both winglet lengths are the 3.5 mm horizontal distance, 7 mm vertical distance, 60o attack angle and 1.25 mm winglet span. Moreover, the thermal performance comparisons between the optimal design of the wavy fin with winglet and normal wavy fin are reported. Wavy fins with winglets provide a larger heat transfer coefficient, pressure drop and j/f(1/3) than those of normal wavy fins. For the j/f(1/3) comparison, wavy fins with winglets provide a j/f(1/3) greater than t
