Which of these is an advantage of the k-ω model over the k-ε model?(

1.	Which of these is an advantage of the k-ω model over the k-ε model?(a) Does not depend on the ε value(b) Easier to integrate(c) Can be applied for turbulent boundary layers(d) Has only two extra equationsThis question was addressed to me in my homework.Enquiry is from Turbulence Modelling in chapter Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct answer is (b) Easier to integrate Easiest explanation: The greatest ADVANTAGE of replacing the ε VALUE with the ω value is that this ω value is easier to integrate. It does not need additional damping FUNCTIONS to integrate. The k-ω model also depends on the ε value for the ω value. Both can be applied for TURBULENT boundary layers. Both has two extra equations.
