Liquid fuels play an important role in the production of pollutants in practical combustion systems. Meanwhile evaporation phenomenon is a key parameter in pollutants emission in the combustion of liquid fuels. Recent studies show that nanoparticles have the ability to change the evaporation behavior of the base fluids. Hence these nano scaled particles may affect the production of pollutants in liquid fuels combustion. Therefore, considering the importance of controlling pollutants emission in the combustion of liquid fuels, in this study the influence of adding aluminum nanoparticles on NOx and CO pollutants emission in the combustion of ethanol and n-decane liquid fuels has been numerically investigated. The results reveal that mass fraction of pollutants NOx and CO will be decreased by adding nano-aluminum to these fuels. These results confirm that aluminum nanoparticles improve combustion features of ethanol and decane liquid fuels.
