Hi,
I have to use this kind of turbulence model, but I have doubts in the way to inizialitze epsilon. I use this formula: eps= 0.09 * ką'⁵ / L; where L is the lenght of the turbulence, I've supposed that is the diameter of my study problem, an injector nozzle. When I do this, it figures a number, but when I run the simulation the results are 4 orders of magnitud higher. This is my problem. Thank you
