- What are the names of the large and small scales of motion in turbulence?
- Derive the small length scale of turbulence in terms of kinematic viscosity and kinetic energy dissipation rate.
- Derive the small time scale of turbulence in terms of kinematic viscosity and kinetic energy dissipation rate.
- What is the Reynolds number based on the small scales?
- What is the ratio of the large-to-small length scales based on the large-scale Reynolds number?
- What does a term like $\overline{u^\prime v^\prime}$ represent physically?
- What are it’s units when multiplied by density?
- How does this compare to the units of the viscous stress $\tau$?
- For a given jet exit diameter, how does the length of a turbulent jet change when the exit velocity/flow rate changes?
- What is a Reynolds decomposition?
- What is a Favre decomposition and why is it used in combustion applications?
