Default multiphase flow modelling, Drag model
Posts: n/a
I would like know which of the following drag models are valid for the densly distributed solid models..?

1. Schiller Naumann

2. Grace

3. Particle transport Drag co-efficient.

4. Isii Zuber (model is only used for non-solid dispresed phase)

I am also interested to know about the Wen Yu correlation for solid volume fractions, since I am concentrating on the flow which has 1 kg /s mass flow(air) at the inlet and 0.3 kg/s solid particlas(spherical,dispersed phase).
