Default Micro Synthetic Jets Boundary Conditions

Hi there,

I'm looking at modeling micro synthetic jets and in the flow domain I was originally using the outflow B/C however as the flow is transient with a velocity of +- 10m/s this results in the fluid being sucked back in through the outlet. Is this a problem? If so how much of a problem? What boundary condition can I use that will get around the reverse flow?

Thanks in advance.
