INFLUENCE OF CONSTANT ELECTRIC-FIELD ON SELF-PROPAGATING HIGH-TEMPERATURE SYNTHESIS WAVE

A model of a heterogeneous medium allowing the action of a constant el ectric field (CEF) on a combustion wave in the condensed phase to be t aken into account is proposed. It is shown that the influence of the C EF on the combustion temperature is of threshold type: At a CEF less t han the threshold, the combustion temperature is constant; above the t hreshold, the combustion temperature falls with increase in CEF. The c ombustion rate falls with increase in CEF; this is associated with slo wing of the reactive diffusion in the combustion wave. On passing thro ugh the CEF threshold, there is a discontinuity in the combustion-rate curve; this is due to additional slowing of the reactive diffusion on account of the reduction in combustion temperature.
