INITIATION OF DETONATION IN HYDROGEN-AIR MIXTURE BY EXPLOSION OF A SPHERICAL TNT CHARGE

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.
