The structure of free turbulent flow is controlled by ___________(a) O

1.	The structure of free turbulent flow is controlled by ___________(a) Only the local environment(b) The source(c) The sink(d) The source along with the local environmentI had been asked this question by my school teacher while I was bunking the class.My query is from Turbulence Modelling in portion Turbulence Modelling of Computational Fluid Dynamics
Answer» CORRECT answer is (a) Only the local environment The BEST I can explain: For a free TURBULENT flow, as the flow progresses, the effect of source degrades. Only the local environment tends to CONTROL the STRUCTURE of the flow at any time. This is inferred from experiments.
