我们研究了微重力下随机排列的燃料液滴阵列的火焰传播特性。在微重力条件下，基于渗流模型计算了均匀分布的正庚烷液滴的火焰传播极限距离。火焰传播概率取决于液滴在晶格中的占有率，并随着液滴占有率的增加而迅速增加。实验研究了微重力条件下非均匀分布正庚烷液滴阵列的局部火焰传播极限距离。液滴以不均匀的间隔成直线排列。非均匀分布的液滴阵列的局部火焰传播极限距离取决于液滴的排列，并且由于相互作用，局部火焰传播极限距离比均匀分布的液滴阵列的火焰传播极限距离大。考虑局部火焰传播极限距离增大时的火焰传播概率大于不考虑局部火焰传播极限距离时的火焰传播概率。
We investigated the flame-spread characteristics of randomly arranged fuel-droplet arrays in microgravity. Flame-spread probability was calculated based on a percolation model with the flame-spread-limit distance of evenly-spaced n-decane droplet arrays in microgravity. Flame-spread probability depends on the occupation fraction of droplets in a lattice and rapidly increases with the occupation fraction. The local flame-spread-limit distance of unevenly-spaced n-decane droplet arrays was experimentally investigated in microgravity. The droplets were arranged in a straight line at uneven intervals. The local flame-spread-limit distance of the unevenly-spaced droplet arrays depended on the droplet arrangement and increased from the flame-spread-limit distance of the evenly-spaced droplet arrays due to interactive effects. The flame-spread probability considering the increase in local flame-spread-limit distance is larger than that without it.
