Results of the experimental studies of the radial electric field effect on the processes of heat and mass transfer and fuel combustion in the flame channel flows are pre-sented here. These investigations demonstrate the field-enhanced variations of the flame temperature and composition profiles and field-enhanced heat generation, which are determined by the drift motion of positive ions in a field direction and momentum transfer to the fuel compounds. It is observed that the field-enhanced radial transfer of fuel compounds reduces a rate of fuel combustion and heat release in a central part of a flame channel flow. This provides reducing the local tempera-ture levels during the fuel combustion and field-enhanced decrease in a rate of NOx formation. Therefore, the results of presented studies demonstrate that the electric field effect on a flame can be used to perform the combustion control. Figs 13, Refs 12.
