摘要：

A model of the spark-discharge initiation of detonation was developed to integrally describe both spark channel processes and detonation initiation processes under the action of a spark-generated shock wave. The consumption of discharge energy for dissociation, ionization, and emission processes and conversion into thermal and kinetic energies with consideration for fuel combustion energy conversion was evaluated. The time history of the spark channel resistance was calculated. The time history of the fractions of energy inputted into a spark and lost for the heating of external circuits with respect to the total discharge energy was determined. Simulation was performed for capacitor discharge in a mixture of hydrogen with oxygen.
