Measurement and analysis of atomization characteristics of oxygenated bio-fuel

  • A pressure-swirl atomizer was adopted to measure the atomization characteristics of oxygenated bio-fuel and its different blends with conventional kerosene RP-3.The study was conducted to analyze the effect of the chemical composition and physical-chemical properties on the atomization characteristics of the oxygenated bio-fuel.For the blends with 50% or less oxygenated bio-fuel, a Sauter mean diameter (SMD) prediction model was developed.The experimental results show that decrease the oxygenated bio-fuel in the blends, the atomization would be improved.In addition, increase the supply pressure drop, the difference of atomization among the fuel blends would be reduced.When the supply pressure drop is larger than 1.0 MPa, SMD of the fuel blends can achieve less than 40μm.By analysis, currently the oxygenated bio-fuel can not be directly used for aero-engine, and the fuel-hydroprocessing or aircraft modification is necessary for meeting the demands of the long-term future aviation.
