Question 1.
What is the difference between rotational flow and irrotational flow?
Show hintHide hint
Consider whether any spinning occurs in the flow.
Question 2.
Define vorticity.
Show hintHide hint
Think about how the fluid particles move.
3Question 3.
What defines rotational flow?
- No vorticity
- Presence of vorticity
- Constant velocity
Show hintHide hint
Imagine a spinning fluid element.
4Question 4.
True or False: Irrotational flow allows the use of velocity potential functions.
- True
- False
Show hintHide hint
Recall the connection between flow types and potential functions.
Question 5.
Given a flow field with vorticity present, how would you determine if it's possible to use velocity potential functions? Provide an example in your explanation.
Show hintHide hint
Remember the relationship between vorticity and rotation.
Question 6.
Discuss the effects of boundary shapes on flow separation and rotationality. Provide real-life examples.
Show hintHide hint
Consider how cars are designed to reduce drag through smooth shapes.
