Question 1.
What is the role of boundary conditions in CFD?
Show hintHide hint
Think about how they affect what happens at the model's limits.
Question 2.
Name one type of boundary condition and its use.
Show hintHide hint
Where does the fluid come from in the simulation?
3Question 3.
What does a boundary condition in CFD define?
- Fluid properties inside the domain
- Fluid behavior at the edges of the domain
- The algorithm used for simulation
- The computational resources needed
Show hintHide hint
Remember the edges of your simulation model.
4Question 4.
True or False: A no-slip condition implies fluid will move at the same velocity as the wall.
- True
- False
Show hintHide hint
Think about how fluid adheres to surfaces.
Question 5.
You are tasked with simulating airflow over a car. Describe how you would set boundary conditions to get realistic drag force predictions.
Show hintHide hint
Think about where the air enters and exits around the car.
Question 6.
In a heat exchanger design, what types of boundary conditions would you apply for accurate thermal performance predictions?
Show hintHide hint
Focus on how heat is transferred between the fluids.
