Hi Rob, thanks for your reply. I have the thermo-physical properties of the nanoparticle. I'm not sure how to add. can you please explain step by step procedure for that. At the moment i have completed Eulerian -Eulerian approch and i have added al2o3 under fluid section of materials. Are you suggesting me to add al2o3 nanoparticle under solid domain. 


Can you please recommed me which model is better suited for nanoparticle sediemntation process.  Thankyou
