Question 1.
What happens to fluid flow when there is a boundary layer separation?
Show hintHide hint
Consider how velocity changes near the surface.
Question 2.
Define favorable pressure gradient.
Show hintHide hint
Think about how it affects flow attachment.
3Question 3.
What is the effect of adverse pressure gradients on boundary layers?
- Increase flow attachment
- Promote separation
- No effect
Show hintHide hint
Think about how pressure affects flow direction.
4Question 4.
True or False: A boundary layer only forms in laminar flow.
- True
- False
Show hintHide hint
Consider different flow scenarios.
Question 5.
Given a laminar flow scenario with a cylinder, predict the effect of increasing the diameter on boundary layer separation, explaining the underlying fluid dynamics.
Show hintHide hint
How does diameter influence flow and pressure around an object?
Question 6.
Design a theoretical model for an aerodynamics application avoiding boundary layer separation. Describe the flow regime and pressure profiles expected.
Show hintHide hint
Consider how different shapes impact the airflow and separation.
