This follows experiments in the lab where piezoelectric actuators were used to induce traveling waves along the surface of an airfoil. It was found that low amplitude traveling waves between 6-10hz would destructively interfere with vortex shedding. This reduced drag and allowed greater AoA.

I stopped storing my Moet et Chandon in pretty cabinets quite some time ago at least, for whatever that's worth. The fridge ended up being a better place for it.
