In this paper we first review our recent work on a new framework for adaptive turbulence simulation: we model turbulence by weak solutions to the Navier-Stokes equations that are wellposed with respect to mean value output in the form of functionals, and we use an adaptive finite element method to c

Many technically relevant Β―ows are wall-bounded Β―ows at high Reynolds numbers. The knowledge of the near-wall behaviour of turbulence is important for the correct modelling of these Β―ows. The inΒ―uence of the Reynolds number on turbulence quantities results from the imposed boundary conditions at the
A new nonlinear near-wall turbulence model is developed on the basis of realizability constraints to predict turbulent flow and heat transfer in strongly nonequilibrium flows. The linear k-e-f l model of Park and Sung (Fluid Dyn. Res., 20 (1997) 97) is extended to a nonlinear formulation. The stress
