4 cards from this section. Quick, good the night before a test.
Define Large Eddy Simulation (LES).
Remember, it's a balance between accuracy and computation.
What is the purpose of spatial filtering in LES?
Think about how we manage computational loads.
What does LES stand for?
Think about how we categorize flows in turbulence.
True or False: In LES, smaller eddies are fully resolved.
Remember the purpose of modeling versus simulation.
Consider a turbulent flow in a pipe. Discuss how changes in the grid size can affect the accuracy of an LES simulation. What could happen if the grid is too coarse?
Think about the relationship between grid size and scale accuracy.
Design an experiment that tests the effectiveness of different turbulence models within LES. What parameters would you measure and why?
Consider what physical outcomes of flow you might observe in differing modeling approaches.
