Question 1.
What is a velocity field?
Show hintHide hint
Think about how we define motion in fluid dynamics.
Question 2.
What does vorticity measure?
Show hintHide hint
Focus on the concept of rotation.
3Question 3.
What is the equation for shear stress in fluid mechanics?
- tau = mu * (du/dy)
- u = -dp/dx
- v = 0
Show hintHide hint
Recall Newton's law of viscosity.
4Question 4.
True or False: Velocity potential can exist in a rotational flow.
- True
- False
Show hintHide hint
Think about vorticity's impact on potential function.
Question 5.
Given the pressure gradient in a two-dimensional flow system, derive an expression for the velocity field and determine how changes in the gradient might affect wall shear stress.
Show hintHide hint
Take careful note of your boundaries and pressure values.
Question 6.
You have a fluid passing a flat plate where the Reynolds number is known. Discuss how altering this would transition through boundary layers.
