AB We propose a model including three equations with two time scales for bubble turbulent homo-geneous deduced by reduction of second order closures in an industrial CFD code (PHOENICS 3.5.1). The viscosity turbulence formulation
introduced by this model releases a compromise between the description level of the turbulence structure for multiphase flows and the easiness of the model use
in many flow cases. The Virtual Reality option of PHOENICS 3.5.1 was used for pre- and post-processing. Model predictions were compared to other flows to prove the univer-sality of the model. This model not only agrees with the data trends, but also predicts the turbulence suppression, which has been measured for high Reynolds number bubbly air/water flows in pipes.
