Keywords: vortex, heat transfer, delta wing, wind and water tunnels

Based on the persistence theory, the vortex is considered stationary, if its translational velocity is less than its rotational velocity. In heat transfer application, the stationary vortex helps increase heat convection. We applied the principles to the heat transfer on the delta wing, where two apex vortices are distinctively present on the suction side of the wing and investigated this behaviour in wind and water tunnels.
