1.	Express the large scale velocity in terms of k and ε.(a) ε^1/2(b) (ε/k)^1/2(c) k^1/2(d) (k/ε)^1/2I have been asked this question during an internship interview.The above asked question is from Turbulence Modelling topic in section Turbulence Modelling of Computational Fluid Dynamics
Answer» RIGHT ANSWER is (c) K^1/2 Explanation: In the k-ε model, the properties of turbulence can be EXPRESSED in terms of the variables k and ε. The velocity scale of the large eddies are GIVEN by k^1/2. k is the turbulent kinetic energy term.
