AGT-1500 Combustor and Fuel Effects Modeling
Abstract
The influence of alternative fuels on gas turbine engine performance is considered analytically. Broad specification or alternative fuels may have viscosities and wider boiling point temperature distributions which adversely affect atomization and vaporization processes within gas turbine combustors, leading to performance penalties in ignition, lean blowoff and combustion efficiency. These performance measures have been modeled by considering ratios of characteristic times which describe the controlling physical processes of fluid mechanic mixing, kinetics and fuel evaporation. Semi-empirical models are developed which describe lean blowoff, ignition and combustion efficiency of the AVCO-Lycoming AGT-1500 combustor and other combustors. These expressions can be used to assist design of fuel tolerant combustors, and to assess impacts associated with fuel type selection.
