Hi Alberto,

So I have made some modifications to the createRASTurbulence.H file, namely the alphaEps coefficient (I believe this is the Schmidt number in the dissipation equation).
It is set to...

Thanks a lot Alberto,

I have compiled the solver again, so basically equations 3.66 and 3.67 (Rusche) are implemented as my turbulence model without the source terms.

The solver now runs on the...

Hi Alberto,

I have finally attempted some modifications to the bubbleFoam solver to implement the mixture turbulence model. I have a question relating to the implementation of the first divergence...

Thank you for the responses Alberto your help is always much appreciated.

I think it may be worth my while to have a look more closely at Gosman's model to hopefully determine what his source...

Well I have read through H.Rusche thesis and the k-epsilon model used in the thesis is Gosman's model. I read your earlier posts as well as the bubbleFoam wiki and I can see that Gosmans model is not...

source terms in bubblefoam implementation of turbulence model

Hi Alberto,

What happens to the source terms in the turbulence model used by openfoam? There appears to be no source terms..

Cheers
