problems in synthetic jet flow simulation
I'm working on the simulation of synthetic jet flow.

my model and boundary conditions:

mesh details:

In this case I used Spalart-Allmaras viscous model and kept other items unchanged.

contours of velocity :
current_time = 0.25s(25 periods)
current_time = 0.2525s(25.25 periods)

Comparing the two pictures above, I find that the jet flow is almost sucked in during the next period. Has I got the synthetic jet flow or just a failed result?:confused:
I'm confused about whether I designed a proper model. And do I have to set other parameters besides the viscous model? (I'm a starter in CFD)
Has anybody ever got experiences in synthetic jet flow simulation? Please give me some suggestions.
Thanks for any replies!
