Hello Foamers!
What I want to ask for is if a solver or tutorial exists where you can model a compressible fluid like air with a moving mesh like a turbine, propeller and finally allows the transfer of heat through a wall, similar to the hotRoom tutorial with the option to use externalWallHeatFluxTemperature? I did try running the movingCone example with the rhocentralDymFoam by changing the object T to this Code:

Hi,
Have you solved the problem? I am new to openfoam and looking for a solver to solve moving mesh both compressible and incompressible with heat transfer. I run my case just for flow with simplefoam and pimplefoam. I wonder I can use buoyantBoussinesqPimpleFoam and buoyantBoussinesqSimpleFoam with moving mesh and MRF? The same question with BuoyantSimpleFoam and BuoyantPimpleFoam? These solvers at the same time will solve flow? Thank you! |
