Heat transfer by Görtler vortices developed on a wall with finite conductivity

Résumé

Görtler vortices are streamline vortices that appear in a flow over a concave wall as a result of centrifugal instability. They have a strong influence on the heat transfer. The purpose of this study is to model the heat transfer enhancement by those vortices using a weakly nonlinear analysis. Computations of basic state coupled with spatial first and second order perturbations provide this heat transfer enhancement, at the fluid-wall interface, as a function of the Prandtl number, the dimensionless wall thickness and the thermal conductivity ratio between the wall and the fluid.
