This photo suggests what happens when a "concentrating" ring with a circular aperture less than the diameter of the TLUD is used:</div><div><br></div><div><img src="cid:F7BE2DBE-B4D1-4522-BDAA-DA48EBF1B9FE" alt="image.jpeg" id="F7BE2DBE-B4D1-4522-BDAA-DA48EBF1B9FE" width="477" height="600"><br></div><div><br></div><div>Looks a lot like an inverted spire of flame that many a TLUD with a concentrator ring ejects.</div><div><br></div><div>My initial tests pouring water out of a TLUD with three deflector washers gives dramatically different results -- as might be expected. The can I am testing with, a small soup can iCan, empties so fast that I am having difficulty getting a good image of the pattern the exiting water makes when I invert the iCan. I will have to make an iCan TLUD with no bottom so I can continuously fill it in order to to properly photograph the discharge pattern the water flow reveals. This will be some weeks from now as I am in Boston and my workshop is in northern VT.</div><div><br></div><div>Cheers,</div><div><br></div><div>Jock</div><div><br></div><div><div>Jock Gill</div><div>P.O.
