The realizable k-ε model is best for predicting __________(a) mixing

1.	The realizable k-ε model is best for predicting __________(a) mixing layers(b) wake formation(c) spreading of jets(d) smooth boundary layer flowsThis question was posed to me during an internship interview.The origin of the question is Turbulence Modelling topic in section Turbulence Modelling of Computational Fluid Dynamics
Answer» Right OPTION is (c) spreading of jets Best explanation: The REALIZABLE k-ε model more accurately predicts the spreading of jets, be it planar or round jets. It performs better than the other models for complex problems involving RECIRCULATION and FLOW SEPARATION.
