Hi all,

I am trying to model natural convection heat transfer of nanofluids inside a square cavity using DPM method. I have following queries regarding that

1) How to convert volume fraction of nanoparticles to number of parcels in case of group injections? For eg: if I want to use 2% volume fraction of nanoparticles of 30 nm diameter, how to create injections for this case?
2) As it is natural convection, initially I need to define a uniform distribution of nanoparticles through out the flow domain.

I strongly believe that, experts here can clarify my doubts. Thank You.
