铝液滴在常重力和失重环境下的燃烧

摘要

A study of aluminum droplet ignition and combustion through an advanced experimental technique in normal and low-gravity environment is presented. It was found that the gravity level greatly influences dynamics of aluminum droplet combustion and morphology of combustion products. In addition,the content and pressure of oxidizing environment also influence sizes,size-distribution,shape of combustion products.%通过一种先进的实验手段研究了铝液滴在常重力和失重两种不同环境下的点火及燃烧特性.结果表明,重力对铝液滴燃烧的动态特性及燃烧产物的形态结构有较大影响.此外,氧化环境的组分及压力也会影响燃烧产物的颗粒尺寸、粒度分布和形态.
