When we consider the momentum exchange between two adjacent layers in a turbulent flow, can it be postulated that if at an instantthere is an increase in u' in the x-direction it will be followed by achange in v' in the y direction?
  • a)
    Yes, in such a manner that = 0
  • b)
    Yes, in such a manner that = non-zero and positive.
  • c)
    Yes, in such a manner that = non-zero and negative.
  • d)
    No, as u' and v' are not dependent on each other.
Correct answer is option 'C'. Can you explain this answer?

When we consider the momentum exchange between two adjacent layers in ...
Ans. (c)
It is postulated that if at an instant there is an increase in u' in the x-direction,
it will be followed by an increase in v' in the negative y-direction. In other
words, is non-zero and negative.
