SPRAY PATTERNATION AT HIGH-PRESSURE

The spatial distribution of the fuel spray created by a gas turbine fuel injector has been measured at high pressure and temperature. A patternation system for measuring fuel-spray mass flux distributions at high-power conditions has been designed and operated. The facility has been designed to simulate the environment inside a gas turbine combustor as closely as possible. Results for a full-scale gas turbine fuel injector have been obtained at high levels of pressure, temperature, and liquid flow rate and compared with visual observations and ambient pressure results.
