4 cards from this section. Quick, good the night before a test.
What is vorticity?
It's related to the fluid's velocity.
Name one application of PIV.
Think of how we track particles in water.
What does vorticity measure?
Think about how we describe rotation or spin.
True or False: Particle Image Velocimetry (PIV) can only measure 2D fluid flow.
Consider how fluid is visualized in real-time experiments.
Given a velocity field defined as V = (y, -x, 0), calculate the vorticity at any point.
Recall that curls involve derivatives of the velocity components.
Imagine a scenario where fluid flow velocities change over time. Define how you would use PIV to track these changes over a 10-second interval.
What technology could you leverage to visualize these changes?
