Nuevos analisis de explosivos

[larean]

ya aviso de que estas cosas siempre se basan en modelos matemáticos horribles

Hago constar que un modelo matematico no es nunca horrible.
Lo que es horrible(mente) complicado es la realidad que intentan reperesentar.
Yo tambien he estado mirando algun libro y en la WEB y la cosa desde luego no es simple.
No obstante, para consumo interno,voy a intentar ver que me sale.
BUEN TRABAJO MISS BERESFORD

Hombre, discrepo. En algunos modelos las matemáticos son horribles.

Esto no es simple, pero está bastante bien estudiado. Un ingeniero de minas me dio un bañito al respecto en otro foro. Para abrir boca:

A detonation wave is essentially a shock within which an exothermic reaction takes place. It involves a wave traveling through a highly combustible or chemically unstable medium, such as an oxygen-methane mixture or a high explosive. The chemical reaction of the medium occurs within the wave, and the chemical energy of the reaction drives the wave forward.
It is also possible for a shock wave in a reactive mixture to initiate combustion (shock-induced combustion), but in this case the shock proceeds at a velocity indicated by the non-combusted mixture, since the actual combustion occurs in the region behind the shock wave, rather than within the wave. The velocity of a shock wave is independent of what is happening after it passes.
A detonation wave follows slightly different rules from an ordinary shock since it is driven by the chemical reaction occurring inside the wave front itself. This change from a shock-induced combustion to detonation happens as the time for the exothermic reaction to occur approaches the time for the shock-wave to pass the reacting particles. Detonation waves proceed at the Chapman-Jouguet velocity, which is a function of the nature of the chemical reaction occurring. A detonation will also cause a shock of type 1, above to propagate into the surrounding air due to the overpressure induced by the explosion.

Lo importante, como puedes ver, es que la onda de detonación está impulsada por la reacción química que sigue ocurriendo, con lo que es distinta de una onda de choque producida por una fuente puntual y dejada, después de ello, a simple propagación cinemática.

No creo que podamos volvernos expertos en ecuaciones aerodinámicas en dos tardes, pero tal vez alguien allá afuera pueda echar una mano.
