Mixing length model cannot be used for _____________(a) turbulent jets

1.	Mixing length model cannot be used for _____________(a) turbulent jets(b) turbulent mixing layers(c) turbulent wakes(d) turbulent flows with separationI had been asked this question in an interview for job.I want to ask this question from Mixing Length Turbulence Model topic in chapter Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct OPTION is (d) TURBULENT flows with separation Best explanation: Mixing length model is ideal for predictions of THIN turbulent shear flows such as turbulent JETS, wakes, boundary layers and mixing lengths. But, they will not be able to PREDICT flows with separation or even recirculation.
