Question 1.
What is the velocity profile for laminar flow?
Show hintHide hint
Think about how velocity varies from the surface to the center.
Question 2.
Define displacement thickness.
Show hintHide hint
It is related to how thick the boundary layer appears.
3Question 3.
What is the velocity profile for turbulent flow?
- Linear
- Parabolic
- (y/delta)^(1/7)
- Exponential
Show hintHide hint
Remember the equation we derived in class.
4Question 4.
True or False: The von Karman momentum integral equation applies only to laminar flow.
- True
- False
Show hintHide hint
Recall the broad applicability of the equation.
Question 5.
Consider two fluid flows over a flat plate, one laminar and one turbulent. How would the drag coefficient differ for both? Analyze and derive a relation based on Reynolds number.
Show hintHide hint
Think about how different velocities affect the drag coefficient.
Question 6.
Given a turbulent flow with a defined velocity profile, find the displacement thickness by integrating over the defined boundaries.
Show hintHide hint
Use the turbulent profile discussed in the lecture for your calculations.
