3 cards from this section. Quick, good the night before a test.
What is mass conservation?
Think about how flow behaves in systems.
Define displacement thickness.
Consider how boundary layers affect flow.
What does mass conservation imply in fluid mechanics?
Think about what happens at any point in a fluid.
True or False: The velocity at a boundary layer ideally becomes equal to the free stream velocity.
Consider how velocity changes near a wall in fluid flow.
A wind tunnel test shows an airflow with a known velocity profile. How do you find the displacement thickness?
Use boundary conditions to set up your integral.
Given a Reynolds number of 120,000, how would you classify the flow in a boundary layer?
Define the thresholds for laminar and turbulent flows.
