A multiphase flow containing dispersed particles may be modeled using either the
particle transport model or the Eulerian-Eulerian multiphase model.
Some advantages and disadvantages of the particle transport model are given below to aid
in the choice of models. The equivalent section for the
Eulerian-Eulerian multiphase model is available in Eulerian-Eulerian Multiphase Versus Particle Transport.
Table 8.1: Advantages and Disadvantages of Particle Transport
|
Advantages |
Disadvantages |
|---|---|
|
Complete information on behavior and residence time of individual particles is available. |
Expensive if a large number of particles have to be tracked. |
|
Relatively cheaper for wide range of particle sizes. |
Very expensive to include turbulence. |
|
Better detail for mass and heat transfer. |
Essentially only possible as a post-process for a large number of particles. |
|
More flexible when there is a significant size distribution
leading to different particle velocities. (In
|
Restricted to low particle volume fractions. |
