Greetings everybody,
I am trying to solve moist air condensation through a nozzle using ANSYS Fluent's WET STEAM model. I have written UDFs to modify the wet steam properties (UDWSPF). In the source term of the 'droplet nucleation' equation, there is a variable 'S' supersaturation which is given by P/Psat. In my case, it becomes Pp/Psat. (i.e) Instead of total vapour pressure, I should use Partial pressure of vapour. Is there a way to modify this built in term ? Or any other alternate suggestions ? |

Hi Wadezaza,
I wrote a 2 UDS equations (exact equations used in wet steam model) and integrated them with the mixture model to solve my problem. I did not use the wet steam model. Sathya. |
