Question 1.
What is a boundary layer in fluid mechanics?
Show hintHide hint
Consider where a fluid interacts closely with a surface.
Question 2.
Define irrotational flow.
Show hintHide hint
Think about fluid movement without any rotation.
3Question 3.
What do the Navier-Stokes equations describe?
- A. Motion of non-viscous fluids
- B. Motion of viscous fluids
- C. Motion of compressible fluids
Show hintHide hint
Focus on the type of fluids they apply to.
4Question 4.
True or False: Irrotational flow has a non-zero curl of the velocity field.
- True
- False
Show hintHide hint
Reflect on the definition of irrotational flow.
Question 5.
Consider flow past a cylinder in a uniform stream. Explain how the boundary layer develops and affects flow separation.
Show hintHide hint
Think about the forces at play and their effects on flow.
Question 6.
Using the Navier-Stokes equations, analyze flow between two stationary plates with a linear pressure gradient.
Show hintHide hint
Start from the basic assumptions: steady flow, incompressibility, and analyze the effects of pressure.
