Ansys Multiphase
 

Hi,
i want to simulate a pipe that contains water! water's temprature is increased by hot air out of the pipe! water is initial at 300K and the air at 2000K! So we have water liquid inlet and water vapor outlet! How can i have this change of water's phase? Help me please!!!!!!!!

I think maybe this would help?

Phases→interaction...→Mass→increase "Number of Mass Transfer Mechanisms" to 1
→From phase2(water) to Phase 1(air+vapor), mechansim: evaporation-condensation

Need more help...

Thanks for your help,
I'm new on ansys. I did that, but i don't know what to do on Boundary Conditions. What phase and what type have to choose at hot air and at water on Boundary Conditions to give initial velocity and temperature?
Sorry for my English...

I want to have only air out of the pipe and change of the phase in to the pipe from water liquid to water vapor!

does your outlet is only vapor?
you should define volume fraction in inlet and outlet

My outlet is only vapor. I want to have phase interaction in the pipe from water liquid to water vapor and only air out of the pipe. I'm new on ansys, can anybody help me?
