2 cards from this section. Quick, good the night before a test.
What does 'k' represent in the K-Epsilon model?
It's related to energy fluctuations in turbulent flow.
What does 'epsilon' indicate?
Think about how energy is converted in turbulence.
What does the 'C_mu' constant represent in the K-Epsilon model?
It's associated with turbulent flows.
Is the K-Epsilon model suitable for all types of turbulent flow?
Think about the specific applications of turbulence models.
A turbulent flow has a turbulent kinetic energy (k) of 1.5 m²/s² and an energy dissipation rate (epsilon) of 0.3 m²/s³. Calculate the turbulent eddy viscosity (nu_t).
Don’t forget to square the k value!
Critique the application of K-Epsilon in high Reynolds number flows. What are the potential issues?
Think of the scenarios where turbulence becomes incredibly intense.
