10.1.2. Rotation

Try these first

1. 1.

   Define boundary layer in your own words.

   Hint

   Consider how fluid behaves close to any solid surface.

2. 2.

   What does vorticity measure?

   Hint

   Think about how fluids can swirl around a center.

3. 3.

   What does the term vorticity refer to?

   • A measure of mass
   • A measure of the rotation of fluid
   • A measure of pressure

   Hint

   Think about how fluids can rotate like a whirlpool.

4. 4.

   True or False: In irrotational flow, fluid particles exhibit rotational motion.

   • True
   • False

   Hint

   Consider what defines rotational versus smooth flow.

5. 5.

   Calculate the circulation around an object in rotational flow and relate it to the vorticity and fluid properties.

   Hint

   Consider the relationship between velocity distribution and the shape of the object.

6. 6.

   Discuss the effects of non-uniform temperature within a fluid on the boundary layer formation.

   Hint

   Think about how heating a fluid alters its behavior near surfaces.
