Dear whoever can help,

I am currently trying to model a simple synthetic jet on my s809 aerofoil. I have extruded a small hole in the surface on the pressure side and am trying to create a boundary condition coming out of it to model a synthetic jet: i.e a 1m/s velocity coming out of the whole. My goal is to see what effect this has on the airflow and boundary layer around the aerofoil.

When i put an inlet or outlet velocity (of the same magnitude as my 15m/s general settings flow) nothing happens. When i did it as a mass flow, the general 15m/s wind flow stopped running???

Could someone please help wtih advice on how to set this up?

Kindest regards Ariel
