3 cards from this section. Quick, good the night before a test.
What is vorticity?
Think about how fluid elements might rotate.
What happens to vorticity in an irrotational flow?
Consider the nature of flow without rotation.
What is vorticity a measure of?
Think about how fluid spins in motion.
In what type of flow is the vorticity equal to zero?
Remember the characteristics of potential flow.
Consider a scenario where you have a swirling fluid with a defined vorticity of 5 rad/s. Calculate how this impacts the shear rate experienced at the fluid's boundary.
Use the relationship between vorticity and shear strain.
If a fluid element in a pipe shows rotational motion contributing to a vorticity of 4 rad/s, explain how this influences the energy loss during flow.
Relate energy loss to turbulence and friction in the flow.
