Modeling Concepts for Multiphase Flow

The Eulerian-Eulerian multifluid models for dense flows where a relatively large number of particles are considered determining a continuous phase in the control volume formulating the governing microscopic model equations. Different [Pg.373]

In the sequel the averaged Eulerian-Lagrangian, averaged Eulerian-Eulerian, and [Pg.374]

In addition to the complex flow structure encountered in these reactor systems, typically one has to deal with component and energy transport within the individual phases and momentum, heat and mass transfer both between the various phases and to the external reactor walls. The interactions with chemical reaction kinetics are difficult both with respect to physical modeling and numerical solution approximations due to the very wide range of time and length scales involved. [Pg.339]

For multiphase systems a rough distinction can be made between systems with separated flows and those with dispersed flows, as sketched in Fig 3.1 (i.e., regime G versus regimes B, C and F). This classification is not only important [Pg.339]

In view of the multi-phase reactor flow structure characteristics summarized in sect 3.1, it is obvious that dispersed flow systems are dominating. For these flows roughly three different computational strategies can be distinguished based on the scales resolved by the model formulation  [Pg.340]

The modeling frameworks used are Eulerian, Lagrangian, or a combination [Pg.340]
