MULTIPLE EXPLOSIONS OF SILANE OXYGEN MIXTURES IN A CLOSED VOLUME

Multiple spontaneous ignitions of silane-oxygen mixtures diluted by in ert gas are observed under certain initial conditions in a closed volu me. Pulsating combustion proceeds isothermally near the first explosio n limit. Pulsation phenomenology is largely governed by the feedback a ttained between the amount and composition of the adsorbed active inte rmediate species and the kinetics of the gas-phase oxidation reaction. Successive explosions occur at various distances from the reactor wal ls and exhibit different spectral characteristics that correspond to t he diverse overall processes.
