Study of Electrostatic Modulation of Fuel Sprays to Enhance Combustion Performance in an Aviation Gas Turbine

Abstract

The influence of electrostatic and electrohydrodynamic charging on hydrocarbon fuel spray patterns and droplet atomization has been investigated. research was performed in a combustion environment with an allison T-56 combustor liner and an unmodified pressure-jet atomizer fuel nozzle. High-voltage probes and a variable-geometry probe insertion device were developed to assess the effectiveness of probe type and location on fuel spray modification and modulation. Exhaust gas temperatures and temperature profiles were measured to determine changes in the combustor's thermal profile and combustion efficiency. JP-4, JET-A and Number-2 Diesel fuels were tested to analyze electrically-assisted atomization effectiveness relative to off-design fuel performance.
