In fluid flow, the boundary layer separation cannot occur___________________?
Correct answer: A. None of these
- A. None of these
- B. At points of abrupt changes in the flow directions
- C. In laminar flow
- D. In case of boundaries experiencing form drag
Explanation
Boundary-layer separation can occur in laminar flow when an adverse pressure gradient makes the wall shear stress fall to zero and then reverse. It is also associated with form drag and abrupt changes in flow direction, so none of the listed conditions excludes separation.
