Hello

 

I am working on two-phase co2. In my study, Co2 as a supercritical enters into the vortex tube and there should be different phases. One in vapor co2 and other is liquid co2. In my RGP table, I generated two table, one for vapor and another for liquid. i know that there should be some liquid drop in the domain. 

According to the following link: I should choose vapor and liquid materials, as well as a homogeneous binary mixture to define saturation properties. (step 2)

!EDIT: Removed LINK

 

So, when I choose for example co2 vapor, co2 liquid and co2mix (homogeneous binary mixture), I define three fluids. What should I do?

The binary mixture is not required as phase. It is just required to calculate saturation properties. Define only two phases.

Thanks for your help.

So, I should add CO2 liquid and CO2 vapor into the FLUID definition. So, how the saturate properties will be calculated?

 

Best regards

They will be calculated via the homogeneous binary mixture you created. 

[abbas]

Thanks for your help. Therefore, I shouldn't need to add homogeneous binary mixture in the fluid definition and the solver find the homogeneous binary mixture in the materials section? And I don't need to define it anywhere else?

 

Best regards

No you do not need it in the domain definition. You Need just to create it as explained int axial turbine stage tutorial.

Dear, sir, could you help me do a tutorial about the CO2 non-equilibrium? especially about the material defined.

Please create a new thread for your question. Check at first the axial turbine stage tutorial.
