Abstract

Abstract: For the great difficulty of preparation of fuel/oxidizer mixtures and stability of the experimental conditions，there are still inadequate studies on the flame speed of large?molecular liquid?hydrocarbon fuels reported at?home?and?abroad. A counterflow twin-flame test-bed suitable for liquid fuels was designed and built，and the unstretched flame speed of n-decane，toluene，methylcyclohexane which are typically alternative fuels of kerosene were obtained. It is found that，under the standard pressure，as the initial temperature of 388K，the maximum of flame speed of benzene/air is 52.4cm/s. As the initial temperature of 378K，the maximum of flame speed of n-decane/air，methylcyclohexane/air are 64.2cm/s，58.3cm/s，respectively.

Key words: n-Decane；Toluene；Methylcyclohexane；Counterflow twin-flame；Flame speed

摘要： 由于实验系统中燃料与氧化剂预混气制备和工况维持稳定存在较大的难度，目前国内外针对大分子液态碳氢燃料火焰传播速度的实验测量结果的报道依旧不多。为此建立了一个针对液体燃料的对冲火焰实验台，并在该实验台上测量了正癸烷、甲苯、甲基环己烷等三种煤油代表性替代燃料与空气预混气的火焰传播速度。测量结果表明，在一个大气压下，初始温度为388K的甲苯/空气预混火焰、初始温度378K的正癸烷/空气和甲基环己烷/空气预混火焰的最大火焰传播速度分别为52.4cm/s，64.2cm/s，58.3cm/s。
