Question 1.
Define displacement thickness in your own words.
Show hintHide hint
Think about how this thickness reflects velocity changes.
Question 2.
What is the formula for the laminar flow velocity profile?
Show hintHide hint
Remember the parameters involved in laminar flow.
3Question 3.
What does the displacement thickness represent in boundary layer theory?
Show hintHide hint
Consider the velocity variations in the boundary layer.
4Question 4.
In turbulent flow, the displacement thickness is typically:
- Greater than laminar flow
- Less than laminar flow
- Equal to laminar flow
Show hintHide hint
Think about how turbulent flow interacts compared to laminar flow.
Question 5.
Given a flow velocity at the edge of the boundary layer and the displacement thickness, design an experiment to measure these effects on drag force.
Show hintHide hint
Consider how varying thickness affects the measured drag.
Question 6.
Analyze how varying the thickness of a plate affects the velocity profile calculations for both laminar and turbulent flows.
Show hintHide hint
Reflect on real-world applications in machinery design.
