Axisymmetric flows

praveen · February 12, 2013, 23:44

Hello
Is it possible to solve axisymmetric flows with SU2 in which there is also a swirl component of velocity ? So velocity has three components to be non-zero but there is no theta dependance of any of the variables.

The axisymmetric with the swirl component is not implemented, but you can always run a 3D case with periodic bc.

Cheers,

So I would make a 3-d mesh like a wedge and apply periodic bc on the two angular faces. Is it enough have one layer of cells in the angular direction ?

The current implementation 2.0.2 requires a hub, and at least 3 cells in the azimuthal direction.

Best,
Francisco
