Which of these does not characterize a turbulent flow?(a) Time-indepen

1.	Which of these does not characterize a turbulent flow?(a) Time-independent(b) Rapid mixing(c) Three-dimensional fluctuation(d) UnstableThis question was posed to me in class test.I'm obligated to ask this question of Turbulence Modelling topic in division Turbulence Modelling of Computational Fluid Dynamics
Answer» Correct choice is (a) Time-independent Easiest EXPLANATION: Turbulent FLOWS are CHAOTIC, diffusive CAUSING rapid mixing, time-dependent as they are unsteady, and involve vorticity fluctuation in all three-dimensions. Turbulence develops an INSTABILITY in flows.
