In this study, by using the empirical correlations for heat transfer and pressure drop and also employing a multi-objective optimization (MOO) approach, the best possible combinations of heat transfer and pressure drop in helically corrugated tubes will be discovered. The design variables are two geometrical parameters of helically corrugated tubes, namely pitch to diameter ratio (P/DH) and rib height to diameter ratio (e/D-H), Reynolds number (Re) and Prandtl number (Pr). The objectives are maximizing the non dimensional heat transfer coefficient (Nu) and minimizing the non-dimensional pressure drop (f Re) in turbulent flow in helically corrugated tubes. It will be shown in the results that by using the multi objective optimization approach, very important relations can be obtained which can be used in the thermal design of fluid flow in helically corrugated tubes.
