Boiling of water with hot air
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!!!:confused:

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

So, I urgently need your help!
