N2 - Increase in energy demand and stringent emission norms drive the need for clean, alternative energy source. Recently, gas-to-liquid (GTL), a synthetic jet fuel produced from natural gas using Fischer-Tropsch synthesis has grabbed global attention due to its cleaner combustion aspects when compared to the conventional jet fuel. The chemical and physical properties of GTL fuels are different from the conventional fuels which could potentially affect the atomization and in turn the combustion characteristics and pollutant formation. In this work the spray characteristics of two GTL blends and conventional Jet A-1 fuels are investigated downstream of a pressure swirl nozzle exit at two injection pressures and the results are then compared. Microscopic spray characteristics, droplet size and velocity distributions are obtained at global as well as local levels of the spray using global sizing velocimetry and phase Doppler anemometry measurement techniques, respectively. Results clearly show that although the GTL fuels have different physical properties, such as viscosity, density, and surface tension the spray characteristics of the GTL fuels are found to be similar to those of Jet A-l fuel.
