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:

    }

    }

    {
        type            inletOutlet;
        inletValue      $internalField;
    }

    farField
    {
        type            zeroGradient;
    }

    back
    {
        type            wedge;
    }

    front
    {
        type            wedge;
    }
}

// ************************************************************************* //
But that caused a crash like this,

Obviously something is missing because I compared the hotRoom fvSchemes to the movingCone, it seems there are too many differences and I'm not expert enough to make those kinds of changes.

Thanks for reading this.

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!

Honestly I haven't looked at this problem since I posted this, other things came up, hopefully someone will spend time helping you with this besides me. I think you should start another thread with your question.
