Numerical prediction of turbulent bubbly two-phase flow in a rotating complicated duct. (English) Zbl 0944.76044
Summary: A fully three-dimensional numerical procedure based on the two-fluid model in a general curvilinear coordinate system is proposed for the prediction of developing turbulent bubbly two-phase flow in a rotating complicated duct. A Coriolis-modified turbulence model is extended to two-phase flows to account for the rotational effect on the lateral phase distribution. The governing equations are solved using a finite volume method with a non-staggered variable arrangement. Comparisons of the predictions with measured pressure and void fractions show good agreement.
