Assuming a flow has a turbulent kinetic energy of 0.5 m²/s² and a dissipation rate of 0.1 m²/s³, calculate the eddy viscosity. What implications does the result have for modeling this flow?
💡 Hint: Remember to identify and separate each variable in the formula.
Discuss how you would approach modeling a high Reynolds number flow using the k-epsilon model. What additional factors would you need to consider for computation?
💡 Hint: Consider the dimensions of the simulation grid compared to the Kolmogorov scale.
