3 cards from this section. Quick, good the night before a test.
What is a velocity potential?
Think about the relationship between potential and velocity.
What is the condition required for a flow to be irrotational?
Recall how we defined vorticity.
What is the primary function of velocity potentials in fluid mechanics?
Think about how you can derive velocities from scalar functions.
True or False: Vorticity must be negligible for velocity potentials to be applied?
Recall the condition we discussed regarding vorticity.
Demonstrate how to derive one velocity component from a given velocity potential. Use φ(x, y) = x² + y² as your potential function.
Make sure to apply the partial derivative correctly.
Assume a fluid field where it shows evident vorticity; explain why velocity potentials cannot be employed effectively here.
Consider how vorticity is indicative of turbulence.
