Question 1.
Define the No-Slip Condition.
Show hintHide hint
Think about how fluid would behave right against a wall.
Question 2.
What does inflow refer to in fluid dynamics?
Show hintHide hint
It's the opposite of outflow.
3Question 3.
What does the No-Slip Condition imply at a wall?
- Fluid has high velocity
- Fluid has zero velocity
- Fluid increases pressure
Show hintHide hint
What would happen to the fluid touching a stationary surface?
4Question 4.
True or False: Inflow refers to fluid leaving a system.
- True
- False
Show hintHide hint
Think about which term means entering and which means exiting.
Question 5.
A rectangular tank is partially filled with water. Design a set of boundary conditions that specify how to treat the water's interaction with the tank's walls and the open surface at the top.
Show hintHide hint
Consider different forces acting at each boundary.
Question 6.
A 2D flow simulation shows unexpected results at wall interactions. How can boundary conditions be modified to rectify this, providing a new predicted outcome?
Show hintHide hint
Rethink the role of turbulence or alternative inflow specifications.
