Abstract
The spray angles produced by fuel nozzles are of interest because they influence the ignition performance and hence the pollutant emissions emanating from fuel spray combustion. Recent studies have indicated that the dispersion of metallic nanoparticles in liquid fuels can affect the fuel spray formation at ambient temperature conditions. Initial results of studies that are evaluating the use of existing phenomenological models to characterize nanofuel sprays are presented here for spray cone angles. Fuel spray cone angles are found to decrease with increasing nanoparticle concentration. These changes are marginal, mainly due to the low nanoparticle concentration values evaluated and ambient conditions of the carrier gas and fuel. These results help to improve the present knowledge of the applicability of such models to nanofuel spray analyses. The suitability of the different models is highlighted and respective implications for their use in nanofuel spray modelling are presented.
