multiphase flow modelling, Drag model
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 coefficient. 4. Isii Zuber (model is only used for nonsolid 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).

Look up the section "Interphase Momentum Transfer Models" in the documentation. Dr. Flow Squad
