RESUMO

In this paper numerical simulations of dispersed particulate two-phase flows, based on the Eulerian − Lagrangian approach, are presented with special emphasis on two-way coupling and turbulence modification. The gas phase was calculated based on the Eulerian approach by solving the Navier − Stokes equations. The disperse phase was treated by the Lagrangian approach. The direct influence of the dispersed phase on the continuous phase is usually taken into account by formulating appropriate source terms for all quantities under consideration. In order to validate the proposed model, the gas-particle flow configuration laden with small particles is considered, namely an axisymmetric particle−laden jet flow and an upward pipe flow Modarress et al. The numerical results show good agreement with the experimental data.
