2 cards from this section. Quick, good the night before a test.
What are large eddies in turbulent flow?
Consider their attributes linked to fluid dynamics.
How do small eddies differ from large eddies?
Think about the Kolmogorov hypothesis.
What type of behavior do large eddies exhibit?
Think about how large structures behave differently in various orientations.
True or False: Small eddies are isotropic and follow the Kolmogorov hypothesis.
Recall the differences noted earlier in the lesson.
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.
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?
Recall the filtering functions we discussed and how they relate to grid scales.
