I'm trying to simulate in CFX the vaporization of liquid nitrogen in a long pipe caused by the heated walls.
Since I'm not very experienced with CFD simulations, is there a tutorial that i could follow?
I have tried using the Ansys Help Documentation to build my simulation, but it still doesn't work.
Thanks in advance!

Plus here's a technical paper from NASA that uses ANSYS Fluent to simulate a nitrogen slosh and boiling experiment.

I still have some problems regarding the evaporation of liquid nitrogen in a heated pipe.
What I'm trying to simulate is the phase change from liquid to gas, for liquid nitrogen entering a heated pipe(T_wall = 150°C).
At first I defined a homogeneous mixture containing the liquid and gas phase and I've set this mixture to the continuous phase. For the fluid pair i've then set 0% mass fraction for the gas-phase at the beginning and 100% for the liquid phase.
I've wanted to ask if this approach is somehow correct or should I use the liquid evaporation model of CFX for this problem?
Or is it possible to simulate the evaporation of a single liquid component into its vapor in Fluent?
I've watched the tutorial above, but since I don't have any droplet injections I'm not so sure if a can set up the simulation in a similar way to the tutorial.
I would really appreciate if someone could help me.
Thank you in advance!
