SOURCES OF ENERGY ABSORPTION OF SPARK DISCHARGE IN DIRECT DETONATION INITIATION

Краткое описание

The work presents the estimate of the distribution of the spark discharge energy throughout different sources of its absorption for the problem of direct detonation initiation. The estimate is obtained by mathematical simulations of both transient process in the RLC-circuit at nonlinear load and gas dynamic expansion of a spark channel in the reactive mixture. The results of oscilloscope recording and photography of the spark channel served as initial data for mathematical simulation. Discharge energy loss due ohmic heating, loss in near-electrode regions, loss due to dissociation and ionization, as well as loss due to uncontrolled energy supply were taken into account.

Ключевые слова: detonation initiation, spark discharge, energy loss
