It's hard to tell from that angle but it looks like the two sides are set at a slight angle. Just not enough— compare to the V-shaped Airtabs.

I don't think anything can act at right angles to the airflow. Any effect will propagate downstream.

If you want to wrap air around an edge, you need the Coanda effect.



Else, cold plasma actuators. Both require energy.
