Transition modeling

Development of a zero-equation transition model


In this project, the local correlation-based one-equation transition model (Menter, F.R., Smirnov, P.E., Liu, T. and Avancha, R., A one-equation local correlation-based transition model. Flow, Turbulence and Combustion, vol. 95, no. 4,pp. 583-619, 2015.) is transformed into a zero-equation transition model. The new model provides an attractive choice in terms of quick implementation of a transition model in existing turbulent flow solvers with Menter’s shear-stress transport (SST) turbulence model, as it only introduces three extra source terms in the transport equation of turbulent kinetic energy.

The details of the model can be found at:

Dynamic system analysis of the developed model.


In this project, the sensitivity of the previously developed zero-equation transition model to different initial conditions, particularly at low freestream turbulence intensity, is investigated using the homogeneous and non-homogeneous dynamical systems analysis
