在高环境温度条件下进行了液滴阵列燃烧的微重力实验。正癸烷液滴阵列悬浮在SiC纤维插入到高温燃烧室，并在一端点燃，引发火焰在高温空气中蔓延。研究了不同环境温度下的火焰传播模式、火焰传播后的燃烧行为和火焰传播速率。实验结果表明，火焰传播模式的出现和火焰传播速率受环境温度的影响。火焰传播速率随环境温度的升高而增大。基于温度对液滴加热的影响和下一个液滴周围可燃混合物层的发展，讨论了这些事实。一个简单的模型来分析这些影响。讨论了火焰传播后环境温度对阵列群燃烧现象的影响以及火焰传播中的尺度效应。
Microgravity experiments on droplet-array combustion were conducted under high-ambient-temperature conditions. n-Decane droplet arrays suspended on SiC fibers were inserted into a high-temperature combustion chamber and were ignited at one end to initiate the flame spread in high-temperature air. Flame-spread modes, burning behavior after the flame spread, and flame-spread rate were examined at different ambient temperatures. Experimental results showed that the appearance of flame-spread modes and the flame-spread rate were affected by the ambient temperature. The flame-spread rate increased with the ambient temperature. These facts are discussed based on the temperature effects on the droplet heating and the development of a flammable-mixture layer around the next droplet. A simple model was introduced to analyze these effects. The effects of the ambient temperature on the appearance of group combustion of the array after the flame spread and the scale effect in the flame spread are also discussed.
