Subject: How's most of the heat transfer to the combustion chamber wall take place?

	When a combustion reaction is taking place like in the 
partially closed combustion chamber of a jet engine and lets say 
the reaction is burning Hydrogen and Oxygen, there is a lot of 
energy that is given off in the form of heat and molecular 
motion. This energy is felt in many ways, one of which is that 
the outside of the combustion chamber gets very hot and when the 
chamber is viewed with an infrared camera then you can see all 
the infrared radiation given off at different temperatures. NOW, 
what I want to know is, is the heating of the combustion chamber 
caused by the infrared radiation given off by the reaction agents 
hitting the chamber walls OR by the high energy molecules 
bombarding the side of the chamber???

AND also, if it isn't really one or the other then what percent 
is the IR and what percent is the molecules?????

Can you also e-mail me the answer if you can answer 
it....Thanks..
