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.

Could you please share the code with me ?

I'm sure many of the members would find this code helpful, so ideally you would upload it somewhere, but if you prefer you can send it directly to me at Bronzemoradian@gmail.com or Moradian@bronze.ir
