3 cards from this section. Quick, good the night before a test.
Define the Closure Problem in one sentence.
Think about what needs to be modeled accurately in turbulent flow.
What does the k represent in the k-epsilon model?
Recall what kind of energy is being discussed in turbulence.
What is the Closure Problem primarily concerned with?
Consider what aspect of flow behavior needs modeling.
True or False: The k-epsilon model is primarily used for laminar flow calculations.
Think about the types of flow described by k-epsilon.
Calculate the Reynolds shear stress for a given set of flow conditions. Discuss how it impacts the overall modeling of turbulent flows.
Use provided equations and understand how to apply them numerically.
Compare and contrast the benefits of using the k-epsilon model versus Direct Numerical Simulation in practical applications.
Discuss scenarios where accuracy is paramount and practical constraints exist.
