I can't quickly find any resources that distinguishes between a 'shock wave' and a 'pulse wave' in the context of explosions. Do you have some resources?
If you're defining pulse wave as a sub-sonic pressure wave, deflagarations can definitely produce those, even with relatively poor fuels (e.g. wood dust). Why do you expect nitrocellulose couldn't? Not enough gas volume?
- naikrovek 3y agoa shock wave is propelled outward by the explosion itself; a shock wave is part of the explosion, the actual gases produced by the explosion being pushed outward. a shock wave moves faster than sound and is usually fatal if you are struck by one. pulse waves move at the speed of sound and are not propelled by the explosion. an air compressor tank rupturing would produce a pulse wave. pulse waves alone are not fatal to humans, though you definitely feel them and hear them.
- hexane360 3y agoI have two questions: - If pulse waves 'aren't propelled by the explosion', what propels them? - Why would seeing a pulse wave in nitrocellulose prove that it's an explosive (as you claim), if you're defining pulse waves as any sonic wave? I'm having a hard time understanding your position, or your reasoning for why nitrocellulose isn't an explosive. I also still haven't been able to find any resources that corroborate what you're saying.
