Adding a source term to the epsilon equation

anon_q · June 26, 2019, 18:40

Hello
In my computational domain I want to add a source term to the $\varepsilon$ equation of the $k-\varepsilon$ turbulence model using the fvOptions framework.
The source term depends on the distance from the inlet and the velocity:

$S_{\varepsilon} = {5x\over U}$

Where

is distance from the inlet boundary condition and

is the local x-velocity.

How can I use fvOptions to achieve that?

Thank you

Hi!

Did you find a solution?

I got the same issue here...trying to add a source term to k-e model?
