Hi Foamers
I have a problem. I have a vessel that it's wall is rotating but I don't know how I could imply rotating wall velocity in OpenFOAM. Can any one help me?
Thanks allot

Dear Ata,

I am not a coder, but do know of a boundary condition in src/finiteVolume/fields/fvPatchFields/derived/... known as "movingRotatingWallVelocity" which exists. I am not able to locate in my 1.5 version, but others are getting it to work.

Best, Lori

Hello lth
Thank you very much.

That's true. I see. It is in OpenFoam-dev not in OpenFoam standard.

Best regards

There is a rotatingWallVelocity boundary condition for in the standard OpenFOAM 1.6 and 1.6.x releases. Apply it like so:

wall
{
type rotatingWallVelocity;
origin (0 0 0); // origin of axis and the axis
axis (0 1 0); // about which the wall will rotate
omega 25; // m/s
}

For moving walls:

wall
{
type movingWall;
value uniform (1 0 0); // wall moving at 1m/s in x direction
}

Hope that helps.

Hello Adriano

Thank you very much.

I'll try it as soon as possible.

Best regards.

Hi Ata,

Ignore the boundary condition for movingWall as it doesn't work. Instead, just set it to fixedValue and provide the correct velocity vector.

Good luck!

Hi Adriano
Thank you very much
So what's rotatingWallVelocity boundary condition for?
Best regards
