Which of the following exemplifies a three dimensional fluid flow ?
Correct answer: A. Fluid flow at the inlet to a nozzle
- A. Fluid flow at the inlet to a nozzle
- B. Fluid flow between parallel plates
- C. Viscous fluid flow between converging plates
- D. None of these
Explanation
Flow entering a nozzle generally has velocity components and variation in all three spatial directions, making it three-dimensional. Flow between parallel plates is commonly treated as two-dimensional, as is the idealised flow between converging plates.
