Vortex-enhanced heat transfer by a new delta-winglet array
Liquid-to-air and phase-change heat exchanger performance is crucial to meet efficiency standards with low cost and environmental impact in numerous end-use energy applications. Research on performance improvement of heat exchangers often focuses on the air side because transport coefficients are …

Vortex generator arrays in air-cooled condensers for power plant applications
… channel with different configurations of delta-winglet vortex generators (VG). A low and high Reynolds number case of 225 and 1123 is simulated which is representative of the lower and upper limits of the air velocity range between 1-5 m/s in a typical air-cooled condenser (ACC) system. …

Effects of Louver Length and Vortex Generators to Augment Tube Wall Heat Transfer in Louvered Fin Heat Exchangers
… augment tube wall heat transfer with the use of delta winglets placed on the fins near the tube wall. These studies were completed on a 20X scale model of a louvered fin exchanger with a fin pitch to louver pitch ratio of 0.76 and a louver angle of 27°, over a Reynolds number range based on …

Practical Applications of Delta Winglets in Compact Heat Exchangers with Louvered Fins
… Recent studies have shown that implementing delta winglets on louvered fins along the tube wall is an effective method of augmenting tube wall heat transfer. In this thesis, the effect of delta winglets is investigated in both two- and three-dimensional louvered fin arrays. For both …
