Abstract

An essential limitation for the accurate prediction of heat transferring equipment is sparse information concerning the effect of the turbulence on convective heat, mass and momentum transfer. This is largely due to the fact that the local transport mechanisms are not yet fully understood, e.g. in laminar boundary layers along concave walls. It is well known that these boundary layers have a strong inviscid instability mechanism due to the presence of centrifugal forces. This centrifugal instability may result in a secondary flow in the form of counter-rotating vortices (Görtler vortices), whose axes are parallel to the main flow direction (Fig. 1).
