Va. Levin et al., INITIATION OF DETONATION IN HYDROGEN-AIR MIXTURE BY EXPLOSION OF A SPHERICAL TNT CHARGE, Combustion, explosion, and shock waves, 31(2), 1995, pp. 207-210
Direct initiation of detonation by explosion of a TNT charge in a hydr
ogen-air mixture is considered. The critical mass of initiating charge
is determined numerically using a finite-difference method based on t
he Godunov scheme, taking into account the real chemical kinetics of c
ombustion of hydrogen in air and the real equation of state for gaseou
s detonation products of TNT. The applicability of the equation of sta
te of a perfect gas to the detonation products of TNT is considered. T
he effective value of the exponent of Poisson's adiabat is determined.
