New advanced k-w turbulence model for high-lift aerodynamics

The development and preliminary validation of a new k-omega turbulence model based on explicit algebraic Reynolds-stress modeling are presented. This new k-omega model is especially designed for the requirements typical in high-lift aerodynamics. Attention is especially paid to the model behavior at the turbulent/laminar edges, to the model sensitivity to pressure gradients, and to the calibration of the model coefficients for appropriate flow phenomena. The model development is based on both analytical studies and numerical experimenting. The developed;model is assessed and validated for a set of realistic flow problems including high-lift airfoil flows.
