引言随着燃烧技术的发展,人们对燃烧液体燃料的燃烧装置中,喷嘴形成的液雾的尺寸分布所提的要求越来越高。首先要求能够测量准确,也很希望建立一些适当的物理模型,能对液雾特性进行理论分析,以确定各种主要因素对液雾尺寸分布的影响。理论模型分析和液雾特性测量结合起来,将大大有助于我们对液雾的认识。这些工作既在工程上有实际意义,又对液雾燃烧的研究的进展起基础性的作用。

INTRODUCTION With the development of combustion technology, the requirements for the size distribution of the liquid mist formed by the nozzles in the combustion device for burning liquid fuel are getting higher and higher. First of all, to be able to accurately measure, but also very hope to establish some appropriate physical model, the theoretical analysis of liquid mist characteristics to determine the main factors on the size distribution of liquid spray. The combination of theoretical model analysis and measurement of liquid mist properties will greatly assist our understanding of liquid mist. These works not only have practical significance in engineering, but also play a fundamental role in the research progress of liquid mist combustion.
