An Analysis of Heat Transfer on a Joukowski Airfoil with Separation and Reattachment.
Abstract
The problem of separation bubbles in subsonic flow has been the object of much attention because of its incidence on the performance of turbomachinery and airfoils in general. An analytical method depicting a two-dimensional incompressible, steady-state flow over the convex side of a Joukowski airfoil on which a large separation bubble has developed is formulated. This method uses a potential flow configuration in cross flow and two equal but opposite vortices at rest behind the cylinder. The vortex strength generating the flow recirculation inside the bubble and the perturbation of the inviscid velocity distribution outside the separation bubble are so chosen that the calculated separation in cross flow occurs at a Reynolds number of 100,000. The average heat transfer coefficient obtained is compared with predicted values of flow separation over a cavity.
