Particle volume fraction calculation in custom drag model.

fyw

Hi,

I want to get particle volume fraction in a custom drag model to simulate drag reduction. But I didn't find this property in the inherent properties. I'm finding it difficult to calculate this in a custom drag model because I don't have access to the other particle information when the drag model is called, and I don't know where to store this custom property.

hi Fang,

Is this for a 1-way (Field data) coupling or a 2-way coupling?  The volume fraction isn't available in the field data coupling, in part as this is only really suitable for cases where the particles don't influence the fluid flow.
