Cavitation with Nitrogen Liquid??

lehoanganh07 · July 17, 2014, 23:57

Hi,
I want to do calculation for cavitation with Nitrogen liquid. But I dont know hoe to chose the material for each phase. As I did with water, in the material panel, I could chose water liquid and water vapor.

But for nitrogen liquid, I saw no option for that. Does any one know how to do cavitation with the nitrogen liquid?

hi
you can add your material to fluent
copy a fluid from fluent database
then in material panel change its name and properties with your favor name and properties then press "chang/create" button!

Thank for your reply!

But the state equation for liquid nitrogen is the equation for real gas, also it very sensitive to temperature, so the density can not be constant.

I tried to use NISF real gas in Fluent data base, but could not use for cavitation model
