Abstract
Vortical structures behind a wing-type vortex generator (WVG) immersed in a drag-reducing flow were visualized with a fluorescence dye illuminated with a planer laser sheet to investigate the enhancement mechanism of heat transfer on the WVG-installed target wall. Particle image velocimetry (PIV) system was also used to measure the flow velocity profiles. Both the flow visualization and the velocity measurement revealed that small amounts of surfactant, Cetyl-Trimethyl-Ammonium-Chloride/ Sodium Salicylate (CTAC/NaSal), added in water changed drastically the flow patterns together with the wall heat transfer distributions due to the reduction of momentum exchange in the vortical flows behind WVG.
