Hello Edward,
I thought that about going larger, only adds to the cooling problem. I had seen
some pretty large figures reported for Nitrous engine L*'s Thank you for the
info regarding the injection scheme. So you have the oxidiser on the outside,
with the fuel encapsulated by it. I had thought to do that the other way
around, to keep the oxidiser off the chamber wall. My researches so far have
led me to look at using a coaxial type with swirl on the fuel. the nitrous
would be through the centre, without swirl. I'm looking at disrupting the fuel
with the nitrous while the fuel is still a wall bounded swirling film.
Carl.

Going larger didn't seem to have any benefit. The injector for these motors
has the alcohol injecting through the center of the nitrous oxide.

Hello,
Thanks for that Edward, that confirms what I thought.

The two motors I've used (2.5"/250lb thrust, 4" diameter/600 lb thrust) have
and L* of ~30. I haven't went any less because everything seems to be working
well.

Greetings,
Can anyone suggest an L* value for Nitrous Oxide with alcohols? I'm thinking
specifically of either Ethanol or IPA.
Thanks in advance,
Carl.
