It is only valid for non-free shear layers and validated for classic boundary layers (wall attached flows). You can give the one equation intermittency a try but you would provably tune the transition onset equation.

Infrared thermography was used to visualize the heating on the upper surface of both wings of the full-span model, and on the fuselage, for angles of incidence ranging from -10° to 10° at a …
Modeling of Flow Transition Using an Intermittency Transport …
WebAmong the currently available transition prediction methods intermittency transport approach has been proven to be a powerful computational tool for turbomachinery applications [4-6]. The recent γ – Reθ transition model which is based on local variables had been validated against a wide range of transitional flows including several low ... Webvelocity Hessian that then transition to an exponential-growth stage driven by the stretching of already strongly bent fluid elements. This transition leads to strong curvature intermittency at later stages, which can be explained by a proposed curvature-evolution model. The link between velocity Hessian to folding hiq multivitamin
