Hello,
Can convective heat transfer within rectangular enclosures filled with naofluids modeling be treated :
1. as a single fluid which has his own physical properties like ( effective thermal conductivity, effective density,....)?!
2. or as two phases (base/ nanoparticles) so multiphase flow? or mixture?
if multiphase way is better , how to insert both properties of base fluid and nanoparticles using Fluent Ansys.
Thank you
Regards.
