Reddit reviews Flammability and Sensitivity of Materials in Oxygen-Enriched Atmospheres, 11th Volume, STP 1479

I like to leave these safety PSAs to you guys.

to /u/Deostructor, water cooling for static biprops is pretty common, but only if you do it right. You're talking about a calorimeter chamber, but you need some pretty uncommon water flow-rates if you do the math. We're talking 100+ gals/min, which is unlikely to appear in a residential/non-commercial setting. Although a Firetruck could probably supply it. [You need to do the math]. Your description of "dump" cooling while using the word "film" is very difficult to understand because "film" cooling is a technical term for a very specific method of cooling liquid-rocket engines. Are you talking about a water-cooled wall combustor, or actually dumping water into your combustor and letting it turn into steam? It sounds like you want to flow water co-axially to your combustor and then just dump it, whereas you could probably run it around a few times in a path to maximize the work of the water and limit the flow-rate you need.

Don't do regenerative oxygen cooling (especially not gox, how would that even be successful). Not with your skill level; not until you can accurately predict heat-transfer rates and material yield properties. Essentially, are you able to do an FEA on your combustor and get meaningful/interpret results? If no , don't try. Oxygen cooled - is a terrible idea. I understand you aren't knowledgeable, but hot GOX is extremely dangerous and hard to work with. This book is a good reference - [http://www.amazon.com/Flammability-Sensitivity-Materials-Oxygen-Enriched-Environments/dp/0803134053/ref=sr_1_1?ie=UTF8&qid=1463944776&sr=8-1&keywords=oxygen+flammability]
