Dear friends,
I want to ask you, if somebody can help me to find some solver in OF (maybe rhoSimpleFoam, rhoPimpleFoam, buoyantSimpleFoam ...). I want to simulate carbon dioxide (CO2) heat transfer to stell tube. There is one picture attachment in my question. My testing case can be described in a few sentences and is divided in two steps: For first steps I want to simulate only flow of CO2 with material properties for constant pressure 10MPa in tube with density, viscosity, therm. cond., heat capacity as a function of temperature. (see attached picture) I want to define this properties through linear piecewise function. And second step is simulation with heat transfer into steel tube. Thank you for your answers, cfdhelp. |

Greetings Ivan and welcome to posting on the forum!
It's very difficult to suggest a specific solver for the first step, because it depends on whether the temperature range is big enough and if the fluid can be considered incompressible or not. My best suggestion is that perhaps you should start off with this tutorial from the wiki: http://openfoamwiki.net/index.php/Ge..._-_planeWall2D - it addresses mostly your second step, but it also gives indications on how to proceed before jumping directly to the final problem. Because it seems to me that you're dealing with a lot of different issues in a single problem and you should perhaps first study how each issue will affect you. For example:
Best regards, Bruno
