Question 1.
What is a structured grid?
Show hintHide hint
Think about regular shapes and their arrangement.
Question 2.
Define boundary condition in fluid dynamics.
Show hintHide hint
It relates to how the fluid interacts with edges of the domain.
3Question 3.
What is the purpose of a boundary condition?
- To dictate the initial velocity of the fluid
- To define how fluid behaves at domain edges
- To calculate turbulence
Show hintHide hint
Think about where the fluid meets its limits.
4Question 4.
True or False: The no-slip condition means fluid velocity is always non-zero at a wall.
- True
- False
Show hintHide hint
Recall the condition related to flow at stationary surfaces.
Question 5.
Given an unstructured grid, explain how you would apply boundary conditions to model a fluid flow problem in a complex domain.
Show hintHide hint
Consider how each boundary impacts fluid characteristics in practical examples.
Question 6.
Discuss the implications of classifying PDEs as elliptic, parabolic, or hyperbolic on the solutions to fluid dynamics problems.
Show hintHide hint
Reflect on examples that fit each classification.
