Abstract:

This report results from a contract tasking M.V. Lomonosov Moscow State University, as follows Plasma chemistry mechanisms for accelerating activation of fuels by projected plasma jets will be investigated by the team of Moscow State University MSU. The approach will exploit excited state transitions and related dissociation processes, instead of the conventional paradigm that uses plasma-dynamic discharge, stimulating fuel ignition with short powerful ultra-violet radiation pulses that creates plasma electrons for the activation. It is envisioned that this new approach will produce substantially more effective ignition than the conventional method at much lower temperatures, at which there is no decomposition of the fuel by radiation. Experimental studies of properties of plasma jets in steady air, theoretical and computational investigations of the activation of air-propane mixture at 300-760 Torr are proposed to test the hypothesis. The effect of plasma activation on the ignition delay time and combustion velocity will also be theoretically investigated.
