An algebraic model for prediction of bypass and separation-induced transition in turbomachinery boundary layers [PDF]
An algebraic intermittency model for bypass and separation-induced transition is presented. The model modifies the production terms of a k-omega turbulence model. It uses only local variables and is tuned for turbomachinery flows.
