Secondary flow injection- Thrust vectoring

[Alex_Dalm]

Hi,

I was wondering if I could have some advise about the best boundary conditions to use when simulating fluidic thrust vectoring with secondary injection of a convergent divergent nozzle. I was initially considering using varying pressure boundary conditions for the secondary injection ( opposing inlet flow direction) in conjunction with mass flow rate at the inlet, but I am unsure of how effective that would be.

Any advise would be greatly appreciated!

Thanks.

Can you suppply a basic sketch of what you are trying to do?

Thanks,

Hi,

The east facing arrow is the primary flow and the northwest facing arrow the secondary injection. I am hoping to find the effect the secondary injection has on the outlet flow.

Thank you.
