dc.description.abstract | Numerical simulations of upward turbulent bubbly flows in vertical pipes are carried
out in the Euler-Euler framework with a low-Reynolds-number (LRN) model for liquid for
various flow conditions. It is found that the correlation for the drag coefficient of a single
bubble in a shear flow, which has been successfully used in numerical simulations with
the high-Reynolds-number (HRN) models, cannot be used with the LRN model. The
reason is an excessive value of drag coefficient of a single bubble in the near-wall cells.
Therefore, a new correlation for the drag coefficient of a single bubble in shear flow has
been proposed. The results of numerical simulations are analysed and compared to
selected experiment results. It is shown that the largest effect of the application of the
new correlation for the drag coefficient of a single bubble in shear flow can be achieved
on the reduction of the relative velocity between gas and liquid. Overall, the results of
numerical simulations agree well with the experimental results. | sr |
