1.	Which of these could not be modelled using the k-ε model, but can be modelled using the k-ω model?(a) Turbulent jet flows(b) Adverse pressure gradients in turbulent flows(c) Boundary layer on turbulent flows(d) Turbulent free flowsThe question was posed to me by my college director while I was bunking the class.My question is taken from Turbulence Modelling topic in chapter Turbulence Modelling of Computational Fluid Dynamics
Answer» Right option is (B) Adverse pressure GRADIENTS in TURBULENT flows To elaborate: For free-shear flows, k-ε models are well suited. But, it cannot model adverse pressure gradients in the turbulent flows. This problem can be overcome by the k-ω model.
