2 cards from this section. Quick, good the night before a test.
What does the term 'turbulent kinetic energy' refer to?
Think about energy involved in motion.
Which model is used primarily for its simplicity in many engineering applications?
Consider which model is more widely discussed.
What is the main function of the k-epsilon model?
Consider what the model's name represents.
True or False: The k-omega model is generally better for low Reynolds number flows.
Reflect on what makes a model effective in low-speed environments.
If a fluid has a Reynolds number of 50,000, what turbulence model would you recommend and why?
Consider how the flow characteristics change with high vs. low Reynolds numbers.
Calculate the turbulent eddy viscosity if k = 0.5 m²/s² and epsilon = 0.1 m²/s³, using C_mu = 0.09.
Break down the equation into manageable parts to solve.
