The present paper considers the intermittency and develops an engineering transition model based on SST turbulence model,by introducing an intermittency factor and following Hassan\'s idea of constructing the transition model.

Application of gamma-theta transition model to flows around airfoils

Based on Menter s SST k-ω turbulence model coupled with Langtry-Menter transition model,the control mechanism of jet-flap,an active flow control method for PAK-B low-pressure turbine blade profile,was numerically investigated under different flow conditions including different cascade inlet Reynolds numbers,free stream turbulence levels,and cascade outlet Mach numbers.

The M-L transition model can somewhat accurately predict the generation and developm.
