Question 1.
What is the kinematic condition in fluid dynamics?
Show hintHide hint
Think about where this condition applies in a water body.
Question 2.
Define dynamic free surface condition.
Show hintHide hint
Consider how waves interact with the surface of the water.
3Question 3.
What does the kinematic bottom boundary condition imply?
- It allows fluid to have infinite velocity
- Fluid velocity is zero at the seabed
- Fluid velocity increases with depth
Show hintHide hint
Consider what happens below the water's surface.
4Question 4.
True or False: The Laplace equation can describe potential flows in fluid dynamics.
- True
- False
Show hintHide hint
Recall the mathematical representation of fluid potential.
Question 5.
Consider a scenario where the seabed has a small breach. How would this affect the kinematic condition you set for the velocity potential?
Show hintHide hint
Think through the implications of changes in boundary conditions.
Question 6.
How would the presence of a floating object modify the free surface boundary condition you apply?
Show hintHide hint
Consider external forces acting on the surface.
