Intermittency-based RANS bypass transition modelling
Summary: A transition model for describing bypass transition is presented. It is based on a two-equations \(k-\omega \) model and a dynamic equation for intermittency factor. This intermittency factor is a multiplier of the turbulent viscosity computed by the turbulence model. Following a suggestion by Menter et al. (2002), the start of transition is computed based on local variables. The quality of the transition model, developed on flat plate test cases is illustrated on turbine cascades.
