Enhancement of heat transfer for turbulent flow in a circular tube exchanger using triangular wing vortex generators (TWVG) is presented Computational Fluid Dynamics methodology. A detailed parametric analysis carried out to evaluate the impact non-dimensional base width (0.059–0.216), height (0.039–0.314) and different attack angle TWVG (α = 22.5°, 45°, 67.5°, 90°, 112.5° 135°) Re 6000–18,000....
