Question 1
What is the primary purpose of Large Eddy Simulation (LES)?
- To resolve all turbulence scales
- To model only large turbulent structures
- To balance computation and accuracy for turbulent flows
💡 Hint: Consider why we need a method that is not as intensive as DNS.
Question 2
True or False: Large eddies are isotropic.
- True
- False
💡 Hint: Recall the differences between large and small eddies.

Question 1
Design an experiment to validate an LES model against experimental data. What parameters would you compare, and why?
💡 Hint: Consider which flow characteristics are crucial for validation.
Question 2
How does the choice of filtering width affect the simulation outcomes in LES? Discuss the implications of too coarse vs. too fine filtering.
💡 Hint: Reflect on the balance between detail and computational load.
