Abstract
A fully three-dimensional numerical procedure based on the two-fluid model is proposed for the prediction of developing turbulent bubbly fllow in a rotating square-sectioned duct. The single-phase nonlinear k-e modelis extended to the two-phase flows. This model yields normal Reynolds stress anisotropies which allow for a more accurate prediction of the secondary fllow and phase distribution in rotating square-sectioned ducts. The primary and secondary flows are predicted well for single phase flow. The numerical results obtained for bubbly flow show trends similar to the measured results for the rotating ducts.
