The above link (to the book) describes various vortex generators, but it doesn’t say much about how much back pressure these generate. I w3as also thinking about the visualisation video. There is some evidence that a convergent mixing chamber is better that a parallel one, and in quantitative terms its interesting to mull this over in conjunction with turbulent entrainment theory.
