Hello everybody,
I actually need to model a natural convection /circulation problem for humid air (mixture of air and steam) in a closed loop. Since I am new in Ansys CFX, I would like to ask, if there is a good tutorial or example for such a problem.
Thank you in advance for your help .

There are tutorials which come with CFX. There are additional tutorials on the ANSYS customer website. They are not exactly what you are looking for but there are buoyancy driven flow examples and multicomponent mixture examples so that is the main physics you need to model this.
