Challenge Problems
Push your limits with advanced challenges
Calculate the energy cascade process between large and small eddies in a turbulent system. Consider energy input from the mean flow to large eddies and the transfer to small eddies.
💡 Hint: Think about the representation of energy levels and how they interact.
Develop a detailed simulation plan using LES for a turbulent flow scenario. What factors would you need to consider for filtering and grid size?
💡 Hint: Recall the filtering functions we discussed and how they relate to grid scales.
