Hello guys,

I have a mixture of water + aluminum oxide nanoparticles. How is it ensured that the mixture has a certain value of volume concentration % of nanoparticles? (mixture model is solves the volume fraction of the secondary phase, which is the nano phase.) If I give an initial volume fraction, it solves all the conservation equations based on it. But is there any way to give input to fluent's mixture model tat has a certain volume concentration % ???

Hi Priyanka.asp

My problem is identicle to yours, were you able to find a solution for the % of nanoparticles?

Any help wud be appreciated, thanks.

Hi atz_33,
I am working on a similar thing on water sand slurry multiphase flow using mixture model. I am not to get desired values for pressure drop. Can you elaborate, what simulation are you working on? and what models are you using?

i am working on the same thing, but i used the VOF which is better than mexture model;;;;;;;;;;;;;

Can you explain me your simulation problem, I mean what are the details of the flow and the details of the problem. My mail id is naiksarvesh@gmail.com. Are you getting results according VOF model ? Thanks..

I`m using mixture model for same problem. I`m having mixture velocity data. For velocity inlet boundary condition, different phase velocity is asked. Is it same as mixture velocity. How to estimate phase velocity from mixture velocity.
