Calculation of Turbulent kinetic energy and dissipation rate

Hello there,
We have gone through many forum projects and found that they have their own k and epsilon values. Please tell or illustrate the formula used to calculate for external flow. Your help will be appreciated.
Thanks

Hi @Harekrishna!

This here might help you: Defining Turbulent Boundary Conditions - let me know if you have any additional questions.

Best,

@jousefm
We gone through it. I have a clarification. How to decide turbulence values for flow over tire.?

Hi @Harekrishna!

I would use the velocity of the inlet that you have set as the boundary condition in your simulation.

Best,

Jousef

This post and topic could help you. :slight_smile:
