Question 1.
What does the acronym NFB stand for?
Show hintHide hint
Think about what happens at the bottom surface of a fluid.
Question 2.
Define the Dynamic Free Surface.
Show hintHide hint
Is it a rigid or flexible surface?
3Question 3.
What does the Bottom Boundary Condition state about vertical flow?
- u·n = 1
- u·n = 0
- u·n > 0
- u·n < 0
Show hintHide hint
Think about how flow behaves at a solid boundary.
4Question 4.
True or False: Dynamic free surfaces can support pressure variations.
- True
- False
Show hintHide hint
Consider how static and dynamic surfaces behave differently.
Question 5.
You have a harbor with a sloping seabed. How would you determine the expected flow speed at the surface given various water levels?
Show hintHide hint
Start by defining your slope and understanding pressure impacts.
Question 6.
A dynamically changing free surface is observed in a wave energy system. Discuss how BBC applies and what factors are most critical in your analysis.
Show hintHide hint
Make sure to relate dynamics with pressure variations.
