Question 1.
Define vorticity and its significance in fluid mechanics.
Show hintHide hint
Think about how it relates to smooth versus turbulent flows.
Question 2.
What are streamlines?
Show hintHide hint
Consider paths traced out by particles.
3Question 3.
What is vorticity?
- A measure of fluid density
- A measure of fluid rotation
- A measure of flow speed
Show hintHide hint
Relates to how 'swirly' the fluid is.
4Question 4.
True or False: All fluid flows are rotational.
- True
- False
Show hintHide hint
Remember the definition of irrotational flow.
Question 5.
Design a flow visualization experiment using the Hele-Shaw apparatus to investigate the effect of an obstacle shape on flow patterns.
Show hintHide hint
Consider both simple shapes (like circles) and complex ones (like airfoils) for contrast.
Question 6.
Given a velocity field, calculate the conditions under which the flow is incompressible and determine the vorticity vector.
