6. 내용 :
Future fuels will come from a variety of feed stocks and refinement processes. Understanding the fundamentals of combustion and pollutants formation of these fuels will help clear
hurdles in developing flex-fuel combustors. To this end, we have investigated the soot
formation and oxidation processes for various classes of fuels, each with distinct physical
properties and molecular structures. The fuels considered include: conventional diesel,
low-aromatics jet fuel, world-average jet fuel, Fischer-Tropsch synthetic fuel, coal-derived fuel,
and a two-component surrogate fuel. Fuel sprays were injected into constant-volume
combustion chamber using pre-burn technique to create high-temperature, high-pressure
ambient conditions. Simultaneous laser extinction (LE) measurement and planar
laser-induced incandescence (PLII) imaging were performed to derive the in-situ soot
volume fraction. Further details of the soot processes were clarified by sampling the soot
particles from within the reacting jet by means of a thermophoretic probe, with subsequent
analysis by transmission electron microscopy (TEM). Correspondence of these TEM images to
the soot volume fraction trend will be discussed. In addition, a brief introduction of current
engine research at the University of New South Wales will be given as well as a general
aspect of Australian automobile industry.
