Sources of help getting started in OpenFoam: nonisothermal viscous compressible 2D?
 
Hello everyone:

I work in C++, but have never used OpenFoam. I have played around with it and it seems feasible to start. There's a particular problem I'd like to address, that I will probably work on for many months. Because of time constraints, I'd like to get some help in setting up the problem:

I am interested in modelling unsteady viscous nonisothermal compressible flow in 2D, with variable transport properties. I would eventually like to model two-phase flow (gas and liquid).

Does anyone know if there is reliable, relatively affordable help out there for setting up this kind of thing in OpenFoam? Or maybe someone has already worked on such a code?

I know there are certain complications in dealing with the kind of problem I'm interested in. I have worked with isothermal, constant-viscosity flows in the past, but have never achieved this level of complexity. So I'd be interested in getting some direction in this regard.

Thanks a lot for any suggestions.

Hello and welcome,

I am not very familiar with your problem but I think you can start with something like compressibleInterFoam. A list of available standard solvers can be found in:
http://www.openfoam.org/docs/user/standard-solvers.php

Other community developed solvers can be found in the extend project:
http://www.extend-project.de/

Most likely you need to combine capabilities from different solvers. With a background in C++ you will be ready to hack your way through the Doxygen manual. Good luck!
