Synthetic Jet Boundary Condition

Karthikeyan D.

Hi all,

I am trying to simulate viscous flow over an airfoil with mass suction/blowing on the surface. I would like to impose this as a surface boundary condition. Right now, i extrapolate density to the wall, give the appropriate velocities (of the jet) and (thus getting all but one of the conserved variables), then get the pressure using:

dp/d(eta) = -rho*(dv/dt).eta_n

where 'eta' is the normal direction and eta_n is the unit normal. Can anybody suggest a better solution for pressure - the normal momentum equation perhaps? Or can anybody suggest where i can look for this?..Am using a structured curvilineat mesh.

Thanks, Karthik.
