ABSTRACT
For the investigation of injection characteristics of fuels in the internal combustion engines or turbines, the thermophysical properties including liquid surface tension, kinematic viscosity, density and refractive index are crucial and necessary for the design and optimization of the fuel injection system. In present study, surface light scattering (SLS) was used for the simultaneous determination of liquid surface tension and kinematic viscosity of the seven binary and two ternary mixtures of n-dodecane, methyl butyrate, and methyl decanoate. By utilizing this apparatus, both properties were investigated in the temperature ranges between (308.15 and 413.15) K for all mixtures and (298.15 and 423.15) K for the methyl butyrate. Additionally, the liquid density and refractive index were determined by a U-tube densimeter between (293 and 423) K and a refractometer from (278 to 358) K, respectively. The obtained surface tension and kinematic viscosity data for the mixtures from the SLS experiment were furtherly correlated by a proposed equations against the temperatures and mole fractions. The density and refractive data were correlated by the polynomial functions. This work provides necessary data and correlation models for the crucial thermophysical properties of the binary model fuels for the bio-aviation kerosene in connection with the investigation of the fuel injection and combustion system.
