Abstract
A model-consistent universal wall-function method for RANS turbulence modelling is presented, which gives solutions almost independent of the spacing of the first grid node above the wall (denoted by y+(1) in plus-units) and allows a considerable solver acceleration and reduction of memory consumptions. Model-consistent wall-functions are turbulence model specific,ensuring almost grid-independent predictions for boundary layer flows at zero pressure gradient, e.g. the flow by Wieghardt . The method is then applied successfully to aerodynamic flows with separation including a transonic flow with shock induced separation by Cook and a subsonic highlift airfoil close to stall by Gleyzes.
