摘要
对使用自由滴落燃烧技术测量喷气燃料辉光度的方法进行了示范.其结果与大型燃烧器试验台架的结果很相近,且与发动机火焰筒的实际温升有很好的相关性.该结果一般与ASTM烟点和辉光值方法是一致的,因此可以用来按工业可接受的标准评定燃料油的质量.此方法先要产生间距适当、大小均匀的油滴流,并在一个有热气流动的石英导管中燃烧.燃烧油滴的辉光度直接用光电二极管测量.在典型发动机的温度范围内进行试验.测量燃料的辉光度可不受喷雾干扰及空气动力学和其它物理结构作用的影响.因为该试验简单、快速,并可以少量样品得到重复的数据,所以它能很方便地被用作实验室方法.
A method for measuring the luminosity of jet fuel has been demonstrated using a free droplet combustion technique.The results compare well with those of large combustor test rigs and correlate well with the combustor liner temperature rises reported for an actual engine.The results are generally consistent with ASTM smoke point and luminometer number methods and are,therefore,useful in assessing fuel quality in light of industry-accepted standards.In this method,a stream of well-spaced,uniformly-sized droplets is generated and burned with flowing hot gas in a quartz duct.The luminosity of the burning droplets is measured directly with photodiodes.The test is performed over a temperature range typical of an engine to measure the luminosity of the fuels free of influences from spray interactions,aerodynamics and other physical configuration effects.Because the test is simple,rapid and gives reproducible measurements with small samples,it can be used conveniently as a laboratory method.
