Fluent_theory__multiphase_turbulence_model
 

I would like to make a question about a multiphase turbulence model that is used in Fluent, the per phase k-e turbulence model. There is not available reference in the theory user guide and I would like to know which author made the extension in the k-e model that deals with the fluctuations of the drift velocity and where can anyone find more information about this model?
