一、引言 为了从理论上计算预报喷雾火焰中的液滴尺寸,研究者们提出许多描述喷雾中液滴的蒸发、着火和燃烧的模型。这些模型大致可分两类:一类是修正后的经典模型,以单个油滴为分析对象,其蒸发模型是液滴尺寸的减小遵从直径平方规律;另一类是以液滴群为对象,考虑液滴之间的相互作用,从而列出一系列数理方程。 I. INTRODUCTION In order to theoretically calculate the droplet size in a spray flame, researchers have proposed many models that describe the evaporation, ignition and combustion of droplets in a spray. These models can be roughly divided into two categories: one is a modified classic model, with a single oil droplet as the analysis object, the evaporation model is to reduce the size of the droplet to follow the square rule of the diameter; the other is to target the droplet group , Consider the interaction between the droplets, which lists a series of mathematical equations.
