I'd presumed a baloney-cut and no boat tail extension. I shall endeavor to find that .OBJ model and update it in Blender. It would be a narrower version of this:
So how do you make a radial Tesla valve? I can see a series of conic sections pointing downstream. If each conic section had a ring of holes around it's base, shrouded by the next cone would that work? |
NB that the ideal BWTB is in fact nothing more than a large (non ideal) "Radial Tesla Valve"..!
If you want to exhaust into a vertical, cylindrical PWTB I would 'go in from the side' as they do in centrifuges.
That 'keeps the momentum' while still giving you the PWTB.
There are all sorts of Radial Tesla Valve designs on YouTube.
But some 1 to 1,5 mm steel plate and strips and the std design can be bent by hand, welded and bolted in place between 2 lids.
(Both Bostik Contact and plain ol gasket maker (get hard but) seal exhausts surprisingly well)
So why complicate things..?
I suppose a pipe bender might be used to make some tubular 'fish hooks' that could each be welded into larger, straight sections of pipe.
Picture those 3 or 4 sided fish hooks all in a row... kinda...
But I think the zig-zag-ey main path of the 2D design is important: That gets any backward flow to 'prefer' flowing along the 'fish hook' as it's in the 'straight line' initially.
Important to note is that any backward flow pulses, are in fact turned into forward flow (with momentum) so the forward flow pulses don't have to 'rebuild their forward momentum..!!!!!!
ie: Why these things are actually more effective at pulsatile flow IMHO..!
