some questions about nano fluids in microchannels
 
Hi all

I want to simulate nano-fluids flow in nun circular cross sections micro-channels with fluent software. I chose a square cross section micro-channel with pure water-AL2O3 nano particles.
I used mixture model to simulate it, but my results are not good. I have some questions and I'll get thankful if you help me .
1-Is it possible to simulate particles with nano dimensions in micro-channels with FLUENT?
2-What is Brownian motion and Is it nessecery to use it in my simulation?
3-Can we use nano-fluids flow in micro-channels on the slip flow regimes?(slip velocity and temperature jump at the walls)
4-In this scale Is there any velocity slip or thermal differences between the phases?

thanks in advance
