9.7. Vorticity and Fluid Rotation

Try these first

1. 1.

   What is vorticity?

   Hint

   Think about the twisting motion of fluids.

2. 2.

   Name one method used to measure vorticity.

   Hint

   It uses particles tracked by light.

3. 3.

   What is vorticity?

   • A measure of temperature
   • A measure of energy
   • A measure of fluid rotation

   Hint

   Think about rotation.

4. 4.

   True or False: Vorticity only applies to non-compressible fluids.

   • True
   • False

   Hint

   Consider different fluid types.

5. 5.

   Given a fluid flow velocity field, calculate the vorticity vector for the flow at various points.

   Hint

   Think about how the curl involves partial derivatives.

6. 6.

   Using experimental measurement data, analyze how different flow velocities influence the rotational behavior of the fluid.

   Hint

   Reference real data from PIV studies to frame your analysis.
