Question 1.
Define vorticity in your own words.
Show hintHide hint
Think about how fluid rotates.
Question 2.
What characterizes a boundary layer?
Show hintHide hint
Consider the effects of viscosity.
3Question 3.
Vorticity is defined as:
- The divergence of the velocity field.
- The curl of the velocity field.
- The speed of the fluid.
Show hintHide hint
Think about the calculation used.
4Question 4.
True or False: Irrotational flow has vorticity.
- True
- False
Show hintHide hint
Recall the definitions we've discussed.
Question 5.
Given the velocity field v = (3y)i + (3x)j, determine if the flow is steady and irrotational, and compute vorticity.
Show hintHide hint
Check the conditions for steady state and use curl to calculate.
Question 6.
Calculate the vorticity components at the point (0, -1, 1) for u = y^2, v = -xy, and w = 0.
