My reasoning for warming the H2O2 was to lesson the energy needed to
boil off the 15% water in it. With the danger of instability removed
(just pretend) if you heated the mix to 102C (or whatever the boiling
point of water is at your tank pressure) then it would flash to steam as
you squirt it over the catalyst. In the real world heating the tank to
these temperature would be impractical and probably be dangerous. Not
being good with thermodynamics I can not say if you would get any net
gain if you were to heat the mix regeneratively around the chamber.
That is superheated after the last valve in the supply chain just before
injection. This might only make sense with a biprop engine.
I had not thought of heating the catalyst, the relatively cool fuel
would cool the catalyst immediately if not for some self sustaining
nature of the reaction, the popping sound reported on start up of a new
pack is interesting.
I wonder at the sequence of events in the reaction. This seems to be
the essence of the thread.
My model before this discusion was of an unchanging catalyst causing
an Oxygen molecule to be striped away from the Peroxide releasing
energy. Some of this energy was given to the resulting H2O molecule to
change it's state to steam (or to keep it's state as steam)
I find it hard to form a mental model now. There are many
possibilities as to what is happening. The formation of H2O might be the
result of the recombining of the Hydrogen and Oxygen after a complete
disassembly of the molecule. The catalyst could be going through some
unnoticed temporary state. Holy quantum physics Batman, I'm going to go
drink some more coffee.
