Rotating wall velocity boundary condition for axisymmetric flow problem

Hello
I am trying to solve flow between two rotating cylinders having a rotating circular ring in the annulus. The cylinder walls and the ring are rotating with different angular velocities. I have taken a wedge shape domain with front and back faces as "periodic walls". This type of flow has non-zero swirl, radial and axial velocities, which do not vary with azimuthal angle. The walls are kept as some temperatures, say 300 K. Hence I wanted to know whether we can apply rotating wall velocity conditions at different walls, in non-rotating frame of reference, in SU2 ? Also, I wanted to know whether we can have single cell in the azimuthal direction ? (between periodic front and back walls) The schematic of the problem is attached with the post. Thanks Anant |

Thanks you for your interest in SU2. The current implementation v2.0.2 requires a hub, and at least 3 cells in the azimuthal direction. It is very easy to impose a different velocity to each surface with a small modification of the subroutine void CNSSolution::BC_NS_Wall(CGeometry *geometry, CSolution **solution_container, CNumerics *solver, CConfig *config, unsigned short val_marker) or void CEulerSolution::BC_Euler_Wall(CGeometry *geometry, CSolution **solution_container, CNumerics *solver, CConfig *config, unsigned short val_marker) for inviscid flows. both subroutines are in solution_direct_mean.cpp Best, Francisco |
