Generalized k−ω (GEKO) Two-Equation Turbulence Model

This paper describes a recently developed two-equation Reynolds-averaged Navier–Stokes (RANS) turbulence model called Generalized [Formula: see text] (GEKO). The model is formulated to include tunable coefficients that can be utilized to adjust the model’s behavior to specific application cases. Contrary to existing models, where model coefficients are inter-related and tightly connected to basic validation cases, the newly introduced coefficients are independent from one another and can be adjusted within given ranges without negative effects on the essential model calibration for wall-bounded flows.
