Fundamental Investigations of Surface Discharges Over Dielectric Liquids for Ignition and Combustion of Fuels

摘要

Nowadays a problem of effective ignition and combustion of fuels is facing a development of new aircraft generation. Our team has undertaken investigation of ignition of different hydrocarbon materials (including heavy hydrocarbons and alcohol) in conditions of pulsed, glow, open and capillary discharges, which showed high efficiency of ignition with their help. At the processes of diffusion of liquid vapors lead to substantial increase of interaction area between plasma and gaseous mixture. The flame front often takes a complicated form. In the present work we start to investigated processes over liquids: water and alcohol (dielectric fuel) and their mixtures- which showed their convenience in experimental conditions. We use water and water-alcohol mixtures to easily visualize hydrodynamic processes over and on the liquid surface; then we repeat these experiments with pure alcohol (and some other dielectric liquids). After these experiments we undertake combustion experiments with pure alcohol (and some other dielectric liquids). In particular in this work we undertake experiments with surface electrode discharge, surface microwave discharge and erosive-capillary discharge.
