TOWARDS A CALIBRATION OF THE LENGTH-SCALE EQUATION

Abstract

A complete set of constraints is proposed to force a high Reynolds number turbulence model to correctly predict the boundary layer behaviour whatever the pressure gradient and the Reynolds number. The constraints are general and are presently applied to a two-equation model, using the Boussinesq assumption together with new forms of the inhomogeneous terms.
