| Popis: | Hot spots important for the theory of detonation and the rate of their growth in a compressed cold explosive determining the induction period of detonation were studied. The numerical gas dynamics procedure based on the EGAK code was used to calculate the evolution of a hot spot taking into account turbulence and heat conductivity. The rate of growth obtained in the calculations, ∼200 m/s, lends support to the hypothesis of a turbulent mechanism of energy transfer when hot spots grow during detonation initiation. |
