Abstract
In this paper, we propose the concept of thermal end-wall contouring (TEWC) as a novel approach to reducing secondary-flow and boundary-layer losses in turbomachines and ducts by means of thermally manipulating the boundary layer. We introduce, for the first time, the general concept of TEWC and provide a proof of concept using the example of a bent duct. The results demonstrate that a considerable impact on the flow field is achieved not only by mean heat flux across the end-wall of the duct, but also by the spatial distribution of the heat fluxes.
