Abstrakt: Multi-walled carbon nanotubes are regarded as promising diesel fuel additives to improve engine performance and emission characteristics. The density and viscosity of multi-walled carbon nanotube blended diesel fuel were analyzed. Flow simulations in the nozzle of an injector Spray A of Engine Combustion Network were performed by using the CFD program Fluent to investigate the effect of introducing multi-walled carbon nanotube to diesel fuel on the characteristics of the internal nozzle flow. The addition of multi-walled carbon nanotubes increases the averaged turbulent kinetic energy of diesel fuel at the orifice outlet in the stabilized injection stage. The presence of multi-walled carbon nanotubes has an insignificant influence on the rate of injection and velocity distribution in the nozzle. [ABSTRACT FROM AUTHOR]
