Question 1.
What is the difference between laminar and turbulent flow?
Show hintHide hint
Think about the patterns of movement.
Question 2.
What is the role of viscosity in the laminar sublayer?
Show hintHide hint
Consider how thickness impacts flow near surfaces.
3Question 3.
What defines the boundary layer thickness?
- Fraction of total fluid volume
- Distance from the surface to where velocity is nearly free stream velocity
- Thickness of the laminar sublayer
Show hintHide hint
Think about where the flow characteristics change significantly.
4Question 4.
True or False: In a turbulent boundary layer, the fluid particle does not experience distortion.
- True
- False
Show hintHide hint
Consider how speed differences can affect particle shape.
Question 5.
A flat plate experiences a laminar flow transitioning to a turbulent flow after certain distance. Describe how you would calculate the boundary layer thickness at a point where the velocity approaches 99% of free stream velocity.
Show hintHide hint
Consider using empirical correlations for boundary layer flows.
Question 6.
Given a velocity profile and the fluid properties, derive the expression for the momentum thickness in the boundary layer.
Show hintHide hint
Think about the conservation of momentum principles.
