Abstract Detailed flow structure in turbulent flows through a rectangular channel containing built-in winglet type vortex generators have been analyzed by
means of solutions of the full Navier-Stokes equations using a Large-Eddy Simulation (LES) technique. The Reynolds number of investigation is
6000. The geometry of interest consists of a rectangular channel with a built-in winglet pair on the bottom wall with common-flow-down
arrangement. The winglet pair induces streamwise longitudinal vortices behind it. The vortices swirl the flow around the axis parallel to the
mainstream direction and disrupt the growth of thermal boundary layer entailing enhancement of… More >
