Density in CFX-Post
Hi.
I'am little confused. I modeled a simple flow trought a pipe. Definded a inlet as total pressure 0,5 atm and a outlet pressure 0 atm, wall, sym etc. and fluid - air at 25 C. Solved it and when I try plot a density in CFX-Post I've got a constant value. So my question is: it is correct solution? How it is looks like with dynamic viscosity and mass flow? I calculated it using Bernoulli's equation and the result was similar. Regards! |
Re: Density in CFX-Post
Air at 25 C is an incompressible material. i.e. density is a constant. The solution is correct.
If you expect density to vary then pick "Air Ideal Gas". |
Re: Density in CFX-Post
Air ideal gas and total energy.

Re: Density in CFX-Post
I have always thought that this was really misleading. Why not calling it "Incompressible Air at 25C". Air by itself is compressible. This is really misleading.
