Abstract

This paper presents the results of numerical simulations of multiphase flow
in ventilation mill-ducts system of the power plant Kostolac B. This flow
of diluted gas and solid piece of coal and sand mixture, was modeled using
software ANSYS FLUENT 12, with a mixture model in the Euler-Euler
approach. Process simulation involves geometry modeling, mesh generation
and tracking trajectory of mixture pieces. A comparison of numerical and
measurement results for the distribution and the speed of the mixture, at the
entrance to the burner, was made.
