摘要: Abstract An apparatus for determining quenching distances reactive gas mixtures was devised. The test bomb is operated at constant volume and designed with electrodes flanged by circular quartz discs 2.54 cm in diameter. Experiments were performed methane, methanol, iso-octane methanol blends over a range of equivalence ratios several mixture initial temperatures pressures. Quenching measured methane agree well previous data. New data are reported blends. fuel found to have larger than either pure fuel. In comparing the empirical correlations such as Daniel or Hicks, et al. it that temperature pressure exponent distance dependent on type.
