| Abstract | Real jet fuels are complex mixtures of many organic components, some of which are aromatic compounds. Towards the high-temperature end of the distillation curve, some of the aromatics may contain multiple rings. A trace amount of these high molecular weight species in the fuel would directly allow for soot nucleation in practical engines especially when the fuel is injected as a spray. This work aims to highlight the variation of the sooting propensity as a function of distillate fractions. Evolution of soot particle size distribution functions (PSDFs) is studied in a series of premixed stretch-stabilized ethylene-oxygen-nitrogen flames doped with Jet A or a certain distillate fraction. Mobility particle size distributions functions, soot volume fraction, and number density are determined by a Scanning Mobility Particle Sizer (SMPS). The results show that the tail end of the distillation curve can produce significantly more soot than the light molecular fraction and the not distilled jet fuel. The implication of the experimental finding on modeling soot formation from real jet fuel combustion will be discussed. |
