inletOutlet B/C doesn't work， cannot stop reverse flow

Hi foamers,

Recently I was applying inletOutlet boundary conditions for stopping the reverse flow when simulating a 2D- rotor section.
However, the case was collapse after running some steps.
The reason is that, the inletOutlet boundary condition doesn't really stop the reverse flow. The a strong reverse flow forms a shock wave, messing every thing up.
Please see the following picture (Attachment 55665).

The boundary condition setup is:

Code:

patch_outlet

{

     type              inletOutlet;

     inletValue     uniform(0 0 0);

}

Could anyone please tell me what's going on with the boundary condition?
I'll appreciate every comment.

Thanks,
Janry

Hi. I'm a begginer but most of my inletoutlet patch contains "value" parameter.

Maybe You should try:

Quote:

patch_outlet
{
type inletOutlet;
inletValue uniform (0 0 0);
value uniform (0 0 0);
}
