I want to know which are the typical values of turbulent kinetic energy (tke) and turbulent dissipation (epsilon) for real simulations?

In an engine, the cylinder average tke and eps peak at 140 m^2/s^2 and 6.5e5 m^2/s^3 while near TDC (before combustion) average typical values are 20 m^2/s^2 and 2e4 m^2/s^3

These values are highly dependend on engine speed, engine geometry (tumble port, ...) and valve lift strategies as well.

Thank you so much! I will try with this values.
