PARAMETERS OF DETONATION-WAVES AT ELEVATED PRESSURES AND TEMPERATURES

Results of theoretical and experimental studies of the most important detonation parameters in gases - detonation front cell size a and the critical energy of detonation initiation E - are presented for variou s initial pressures and temperatures of mixtures, including detonation waves in shock compressed gases where these two initial parameters ch ange simultaneously. The relative decrease of the cell size in detonat ion waves spreading through a gas behind incident or reflected shock w aves is of the universal nature for different mixtures and initial pre ssures (within the range of shock wave Mach numbers studied). This ver satility of the dependence holds also true for the relative decrease i n the critical energy E.
