No. 19,4 (1976) which maintain the fireball and can extend its duration to between 10 and 50 ms as exothermic recombination reactions occur.May L.Chan (2001) Advanced Thermobaric Explosive Compositions. Further damage can result as the gases cool and pressure drops sharply, leading to a partial vacuum. This rarefaction effect has given rise to the misnomer "vacuum bomb". Piston-type afterburning is also believed to occur in such structures, as flame-fronts accelerate through it..
