Hi, all In CFX v10.
I want to know that the vortex shedding arise in a sharp edge of sudden expand internal flow channel. (Re:3x10^3, air, sudden expand channel, SST model, fine mesh in the wake and edge, yplus <1) Kelvin helmholtz instability must be necessary to do? my inlet flow is as followings. Uy=C*sin(2*pi*t/T) |

Hi,
Good quality mesh, fine enough timesteps, second order time and space differencing, simulation domain large enough. Glenn Horrocks |
