Question 1
In a specific case study of a turbulent jet, describe how you would implement LES. What factors would you consider in your filtering approach?
💡 Hint: Think about the relationship between grid size and the scales of turbulence.
Question 2
Evaluate a scenario where a universal turbulence model fails. What does this imply about the behavior of larger eddies?
💡 Hint: Reflect on the characteristics of large eddies compared to small ones.
