This is SWEET!! And, the amazing thing - well, it's not 'amazing,' is that I read this paper perhaps 2 days ago!!
Dankeschon for the graphs and the information/data!
By 'temperatures,' I was thinking about Chamber Temperature; with your ~ 10 C, are you referring to your N2O - correct me if I'm wrong!! - delivery Temperature??
If, empirically, you 'came very close to the calculations,' well, congratulations are in order!! And - and - you've survived to tell the tale!!!
I will certainly post some photos, and some data, as I continue to work! Thanks for the invitation! Sometimes, I find, the simple fact of the genuine interest and curiosity of another human is Tremendously Encouraging!!! Danke!!!
May I ask what your ABS Cross-Section and/or Port(s) Design looked like?
Yesterday, I tested some solid Polypropylene with GO2, in a single port vs multi-port configuration. Flowed 100% O2 at 10 L/ min. All controlled.
Single port was simply a single 9/32' hole in a 1.75" diameter 6 cm long solid PP Rod.
Multi-port was 5 ~ 1/8 ports in the an identical 1.75" diameter 6 cm long solid PP Rod.
The total open area (total open area of all ports combined) in the latter case = the cross-sectional area of the 9/32" single port.
Burned both under identical conditions, circumstances, environments, etc. for exactly 60 seconds. These are end-burning, in that the GO2 is injected at the base, and the combusting surfaces / surface area is at the very opposite end.
Calculations show that the available surface area for GO2 + PP combustion is identical, and the O2 flow rate is identical.
The Mf (fuel mass) consumed in the multi-port end burning sample was 26% greater than the Mf consumed in the single port end burning sample.
