Question:-
In a turbulent flow, `u, `v and `w are time average velocity components. The fluctuating components are u, v and respectively w’. The turbulence is said to be isotropic if
Option (A)
`u = `v = `w
Option (B)
`u + u’ = `v + v’ = `w + w’
Option(C)
(`u)2 + (`v)2 = (`w)2
Option(D)
None of the above situations prevails
Correct Option:
(B)
Question Solution:
Turbulence is said to be isotropic if `U + u’ = `V + v’ = `W + w’
