Question 1.
Define boundary layer.
Show hintHide hint
Consider the relationship between flow and surfaces.
Question 2.
What is displacement thickness?
Show hintHide hint
Think about the distance affected by the boundary layer.
3Question 3.
What does the boundary layer refer to?
- A flow area far from the object
- A thin region near the surface where viscosity matters
- A turbulent flow region
Show hintHide hint
Revisit the definition from our notes.
4Question 4.
True or False: Displacement thickness accounts for the change in pressure in a boundary layer.
- True
- False
Show hintHide hint
Focus on the definition and concept of displacement.
Question 5.
Determine the momentum thickness for an incompressible flat plate flow given a parabolic velocity profile and conditions around it.
Show hintHide hint
Set up the integral formula properly considering the limits from zero to the boundary layer thickness.
Question 6.
Analyze how displacement thickness would change if the free stream velocity increased significantly and discuss the implications.
Show hintHide hint
Consider the relationship between velocity and effects on the flow structure.
