This is one of many tests I use to see the cooling performance. This is called a Shrunken overhang test: thingiverse.com/thing:6315375
VaLvNaToR can do this in ~2:30 and have been as low as 2:15, see other video on this channel. So that is my reference, for this test, in comparison. This one was 2:38!!!
I went to the 8 orifice in order to get more volume. The 4 hole was in the range of ~60GPM, and the 1st revision of the 8 hole was 78GPM. I have not tested the 3rd revision yet, but it also has some shape changes to allow more flow as well. Low speed is very uniform ring and nice center pocket.
What's holding it back now is the angle of the nozzle orifices. Trying to keep this compact so I don't have to keep increasing Z/height distance of the duct.
