论文摘要
多分散燃料的粒度分布（PSD）的动力学对于评估燃烧过程很重要。在本文中，我们展现了PSD代表的动态的奥秘，并在点火过程中获得了对液滴行为的新见解。多分散性的简化模型用于描述线性区域附近的系统，该系统会演变为描述PSD的时间依赖函数。我们检查了实验以及松蛋白 - 拉姆勒，nukiyama-tanasawa和伽马分布近似值的初始PSD的PSD uccuation。结果表明，在点火过程中，液滴半径如预期的那样减小，但是较小的液滴的数量增加与半径的反相反。图表可视化的一个重要的新颖结果是液滴的平均半径，该半径是通过减少而首先增加射击时间的时间。最后一个结果表明，平均半径的最大值未在过程的开头位于预期。此处介绍的算法优于包裹方法，因为它可以使用可忽略不计的计算时间来应用PSD的任何近似值。
The dynamics of the particle-size distribution (PSD) of the polydispersed fuel is important for evaluation of the combustion process. In this paper we unfold the mystery of the dynamics represented by the PSD and gain new insight for the droplet behavior during the ignition process. A simplified model of the polydispersity is used for describing the system near the linear region, which evolves time depended function which describes the PSD. We examine the PSD uctuation in time of the initial PSD described by the experimental as well as the Rosin-Rammler, Nukiyama-Tanasawa and the gamma distributions approximations. The results shows that the during the ignition process the droplets radii decrease as expected, yet the number of the smaller droplet increase in inverse proportion to the radius. An important novel result visualized by the graph, is the average radius of the droplets which first increases for shot time following by decreasing. The last result show the maximum of average radius is not located at the beginning of the process as expected. The algorithm presented here is superior to the parcel approach, since it can be applied for any approximation of the PSD, with negligible computation time.
