Hi, don't know about Comsol CFD but Fluent cannot model nanofluid.

Florent Malloggi

If continuum assumption is no longer valid Comsol should not be able to model it. The continuun limit is around few nanometers for NS so below this limit you must use another numerical simulation method like molecular dynamics.

Ahmad Faris Ismail

Any CFD code that can model this phenomenon?

Another question comes up: should we treat nanofluids as Newtonian fluids?
