Effects of fuel physical properties on direct injection spray and ignition behavior

CFD simulations of reacting fuel sprays were conducted to identify temperature-dependent physical properties of the liquid fuel that should be emulated by diesel and jet fuel surrogates during compression ignited combustion. Using a validated CFD model for an n-dodecane spray under diesel-relevant conditions, six physical properties of the liquid phase fuel (density, vapor pressure, viscosity, surface tension, heat of vaporization, and specific...
