2 cards from this section. Quick, good the night before a test.
Define laminar flow.
Think about the fluid behavior at low speeds.
What is displacement thickness?
It relates to how the flow changes around an object.
What characterizes laminar flow?
Recall the flow patterns at low speeds.
True or False: Displacement thickness accounts for the volume of fluid displaced due to a flat plate.
Think about how streamlines behave near boundaries.
Calculate the boundary layer thickness for a flat plate in a wind tunnel with a uniform speed of 4 m/s assuming kinematic viscosity is 1.5 × 10^-5 m²/s.
Evaluate Reynolds number first.
Given a momentum thickness of 0.002m, how much momentum deficit does this indicate for the flow?
Consider averaging the velocity profile.
