Abstract

A dispersed flow model a two-fluid model for a gas-liquid two-phase flow problem. This dispersed flow model is compared with a single pressure model used generally by adopting higher-order up-wind schemes for the advection terms. They are Kawamura-Kuwahara, UTOPIA, QUICK and the second order up-wind schemes. Analyses were carried out for a bubbly flow injected from a small circular central bottom wall of a cylindrical vessel.<BR>The computation for the dispersed flow model is more stable than the single pressure model. The QUICK scheme gives the best agreement with the measured results of the four schemes.
