Hello, I am trying to use field function to add an additional source term Srans into the k and w equations.(as shown in the equations) The Source terms are to take account the extra bubble induced turbulence. It is two phase flow with Euler-Euler SST model.
I think the right way should be using field functions, but I don't know how can I incorporate my new filed functions into the iterations and calculations. Great thanks for any help you could give
I have attached the equations.

The equations are from Ma et al(2017)Direct numerical simulation–based Reynolds-averaged closure for bubble-induced turbulence,PHYSICAL REVIEW FLUIDS
