size particles in DPM
 
hi dears
can I simulate nanofluid with DPM ?
I read some text that said it is accurate for low volume fraction (less than 10 ).
but I read some text about DPM that said you cant use DPM for nanosized.
please help me .
thanks

I think so, as long as the volume fraction is really small (<0.12), I think it is OK with DPM. But there may some problems with the interaction.
