Model for Mixing two fluids at near molecular level

Jegan · May 20, 2019, 14:08

Hello all,

I want to mix two fluids(Liquid kerosene(spray)-air) at near molecular level in fluent. which will be a appropriate model to simulate this.
Any suggestion please...

Thank you.

you can use ..multi phase model with mixture you can use or volume method u can use

Thank you for your kind reply,

But multiphase models mix the fluid in macro level right? correct me if I'm wrong.
then how can I spray liquid if I choose multiphase model …please tell me your valuable suggestions.

Thank you
jegan.

The fluid particle model is macroscopic. We do not talk about molecular effects in a fluid except via other models. Spray modeling, chemical reactions, etc. are all modeled at the macroscopic level in fluids. If you want to simulate molecular stuff, go somewhere else.
