2 cards from this section. Quick, good the night before a test.
Define the term 'boundary layer'.
Consider what happens in fluid flow near surfaces.
What does Reynolds number indicate?
Think about flow behaviors.
What is a boundary layer?
Focus on the fluid's proximity to a solid boundary.
True or False: Higher Reynolds numbers lead to thicker boundary layers.
Consider how flow regimes change.
A flat plate has a flow of water over it with a Reynolds number of 2x10^5. Calculate the estimated boundary layer thickness assuming k=0.38.
Use the boundary layer thickness formula from the section.
Discuss how you would approach analyzing a boundary layer around an aircraft wing if numerical flows were to be unsuitable.
Consider what happens with thick boundary layers or flow separations.
