I would like to work on a case including boiling of water. I have looked at the test example of boiling of water in the installation directory and it works fine for me and I understand it fully. It consist of "Water at 100C" and "Water Vapour at 100C".
Now I want to add a 3rd phase which is pure "air ideal gas". In my specific case I use the hot air to heat up water until it boils. The water enters a duct with hot air which make some of the water boil and form vapor.
But I cannot setup my case since I have 2 continuous phases. Is there a correct way to set up my case? please advice

Hi, does the boiling model in the installed directory really fill you?
I am searching for a well boiling model, but there are some problems!

one case, the water tempreture reaches 590k, and there have no water vapour!!!

another case, without heating, the water was boiling, and the curves are wrong!!!

So, I urgently need your help!
