where "e" is the Euler's constant, [P.sub.VN] is the von Neumann borehole pressure at the detonation front
produced by the explosive, H(t) is the Heaviside unit step function, n is an integer, and [gamma] is a pressure decay parameter.
Aluminum in its powdered form generally does not react quickly enough to contribute to the detonation front itself ; however, it can react in the products of the condensed phase explosive or in the surrounding atmosphere, significantly contributing to the strength and acceleration of the blast wave.
The flow behind the detonation front of the aluminized explosive is more complex than the flow behind the detonation front of an ideal explosive.
The newly formed detonation front runs towards the end wall where it causes an enormous pressure rise.
While the detonation front moves through the gap between the obstacles into the unburned gas (t > 12.48 ms), the opposite front of the reaction wave ("retonation wave" ) runs backwards and consumes the remaining fresh gas in the lower part of the channel.
The energy from these reactions causes the star to expand, changing its density and allowing a much faster-moving detonation front
of nuclear reactions to occur.
The burning explosive acts on the surface of accelerated material in the plane of detonation front (Chapman-Jougett plane) by pressure [p.sub.cj].
where [w.sub.d] [m.[s.sup.-1]] is the velocity of detonation front, [beta] [[degrees]] is the bend angle.
At removal from stoichiometric ratio of fuel-oxidizer to concentration limits the regimes with an unstable detonation and lengthy zone of forming of detonation front
