hello
I am looking for the best simple way to simulate a fan in a 2D domain. ![]() Solver : buoyantPimplefoam My domain have an inlet and outlet (classical) In this domain, I would like to introduce a fan with : - at fan inlet the conditions of the domain - at fan outlet a fan condition with forced speed, outlet temperature = inlet temperature ie the temperature of the domain above the fan.. No need of dynamic mesh Has anyone seen it before ? what is the easyest way ? thanks a lot and happy end of year !! ![]() ![]() mat |

Hey,
If you do not need the "real" behavior of the fan (with the blades, rpm, hub diameter etc), you can create cylindrical cellzone in which you apply a fixed velocity constraint matching the airflow created by your fan, if known. If you have all the specifics about the fan, there is a fan boundary condition: https://doc.openfoam.com/2312/tools/...d/coupled/fan/ You need to create a circular facezone matching the fan's diameter, and convert it to baffles. Check out the tutorial mentioned at the bottom of the link ![]() |

Hey,
You should share more information about the issues you are running into, it is quite hard to tell what is wrong from your last post ![]() Have you run the tutorial I mentioned (link in my last post)? If you have not, please do and study the files, it will help you more than I can. |
