Abstract: In this study, the effects of the wing-width ratio (0.31, 0.47, and 0.63) on the heat transfer and fluid flow characteristics of the heat exchanger and the results were compared with those obtained for a plain tube and tube with longitudinal strip (L-S) insert. The comparison was also done among the thermal performance of plain tube, tube with longitudinal strip (L-S) insert, T-W tape semi-circular insert. At last the results of the Nusselt numbers and friction factors with those predicted by standard correlations for a plain tube were validated. The results reveal that the wing-width ratio of the T-Ws significantly affects the flow characteristics and the effect of the wing-width ratio on the friction factor is dependent on the Reynolds number. It was found that lowest thermal performance factor is obtained for the tube with L-S insert.
Keywords: wing-width ratio, heat exchanger, thermal performance, Nusselt numbers, friction factor.
