Tesla Valve Flat Split Half

This is a flat design that can be CNC made, and the two half's bolted together before welding onto flange plate. Looking at the flute width and neck this design cannot be made with 21mm depth, will have to make in 5 sections of 8.4mm depth +2mm base (added this stl too)
Again the idea is to test the design in a valveless pulse jet to see if it adds any benefits.
The intake area is 522.93mm2 which is very close to the area of the 1" 1/64(25.7696mm) which is 522.67mm2
