help for multiphase modeling
 
Hi everyone! I am going to perform a multiphase flow with work medium CO2, CH4, CO, N2 and wet steam considering wet steam condensation using CFX 11.0. I create a fixed composition mixture with CO2, CH4, CO, N2. And then import the iawps library work steam3v, steam3l and steam3vl. but during the multiphase setup process, in the "fluid pairs" index, a default mass transfer model is setup between the fixed compostion mixture and steam3l.

However, there is no mass transfer between the composition mixture and the steam3l.

How I can deal with the problem?

Thank you in advance.

Regards, Lan

wet steam model
 
hello,
i try to model the real gas that contains water vapor and another components that condensation of water vapor is occurred.
i want to use wet steam model and use srk eos as the udf.
please aware me if i can. and why not.
thanks a lot

hi salam....
i m also working on realgas which is partly condensed air.this case includes both vapor and liquid phase. i wrote my udf for single phase. can u help me for two phase of same....
thanks
