Have you made a rotationally symmetrical version of that flow, or are you going to try to make flattened jet? The biggest problem I've seen with valveless jets like this are that it works great in 2d, but rectangular cross-sections don't do well under high-pressures.

I have done lots of experiments with 3D versions of this valve. I even did some with a traveling rotation along the axis, so that it looked like a helix. Unfortunately, those were duds, though the looked beautiful.

My current jet engine work does not include a Tesla Valve, though much of it is inspired by it. When I began, I imagined using a pulse jet, and attaching an axialy rotated tesla valve to the front of it, in order to replace the reed valves. I eventually moved away from pulsed combustion though. Too noisy and not the pressure levels I wanted.
