Hello guys

I am solving a condesation process in a shell(with a single helical tube in which cool water at 10degrees in moving) and tube surrounding the hellical tube, the tube is with hot moist air say around 80 degrees.
I am doing mesh in ICEM-cfd, and CFX solver.
but because iam totally new to this kind of problem I tried to search in tutorials and google but could not find any of such.
So please do help how to solve.
I did meshing in ICEM-cfd and while solving.. which model need to solve,
either homogenious or non homogious and specifing the domain fluids
water and air how to proceed with interface ? between shell and tube?
but i have only one surface to specify interface between shell and tube
please update on condesation processs.
how to proceed in CFX to solve this.
Thank you,

It sounds like you are beginner in CFD so you need to take the problem on one step at a time. Firstly you need to be competent at single phase simulations. Then move onto Conjugate Heat Transfer (CHT) simulations which have a solid domain and a fluid domain. Then look at the multiphase side of things - this step is by far the hardest.

You need to look in the academic literature to find people who have modelled this type of thing before the best idea of how to proceed.

I expected first reply from you, and I am thankful to you,
I have knowledge on CFD but thing is I am know a little in CFX, and Multiphase,
Yes I want to improve knowledge on MULTIPHASE MODELING.
ACADEMIC LITERATURE. can u help me where can I find them.
because I have 10 days time to get knowledge on this subject.
Thank you,

Try google scholar, academic journals and your local university library.
