N2 - Recently, several studies have demonstrated that the addition of nanoscale high-energetic metal particles to liquid fuels as fuel additives has a positive effect not only on the combustion performance but also in reducing the pollutant formation. However, most of those studies were performed for conventional fuels with high volume concentrations of nanoparticles, which will have a considerable effect on the hydrodynamic and thermophysical properties of the fuel. Such a change in fuel properties can in turn affect the atomization, mixing and evaporation characteristics of the liquid fuels. This study investigates the spray performance of an alternative gas-To-liquid (GTL) jet fuel with the addition of alumina nanoparticles at atmospheric condition and compared with that of the pure fuel. Macroscopic and microscopic measurement of the spray characteristics are performed using optical diagnostic techniques. Results show that the addition of nanoparticles tends to reduce the liquid sheet breakup length when compared to that of the pure fuel case. Furthermore, the droplet size and droplet velocities are observed to be slightly different between the pure fuel and nanofuel cases.
