Question 1.
What is displacement thickness?
Show hintHide hint
Think about how viscosity affects flow near a surface.
Question 2.
Define momentum thickness.
Show hintHide hint
Reflect on how viscosity changes the flow dynamics.
3Question 3.
What is the displacement thickness?
- A measure of speed
- Thickness of the... interface
- Distance a streamline moves from the wall
Show hintHide hint
Recall what happens to streamlines near surfaces.
4Question 4.
True or False: Momentum thickness accounts for reduction in kinetic energy due to boundary layer.
- True
- False
Show hintHide hint
Differentiate between momentum and energy definitions.
Question 5.
Given a velocity profile u/U = y/delta, determine both displacement thickness and momentum thickness.
Show hintHide hint
Focus on the integration method employed in class.
Question 6.
In a scenario with variable viscosity, explore the implications on momentum and displacement thickness. What changes occur and why?
Show hintHide hint
Assess how fluid dynamics and viscosity relate to thickness measurements.
