We studied fuel atomization in an air-assisted atomizer of aircraft engine with volume-of-fluid method in microgravitation approximation under the conditions closer to the ones of the operating cruise mode. The problem was looked upon in a two-dimensional axisymmetric configuration, including the simulation of the swirl velocity and in a three-dimensional configuration. We found a drop-size distribution function and spatial distribution of kerosene in an atomizer, which was designed by the engineers from UEC-Aviadvigatel JSC. We have hypothesized the formula connecting the drop-size distribution function obtained in the three-dimensional configuration with the distribution function obtained in the two-dimensional configuration. Along with that, the spray half angles found in these configurations appeared to be the same, although, generally, there is a difference in spatial distribution of kerosene drops.

膜体积法模拟预成膜空气辅助雾化器中的一次膜雾化

我们在更接近工作巡航模式的条件下，利用流体体积法在微重力近似中研究了飞机发动机的空气辅助雾化器中的燃料雾化。该问题是在二维轴对称配置中进行的，其中包括涡旋速度的模拟和三维配置。我们发现雾化器中煤油的液滴大小分布函数和空间分布是由UEC-Aviadvigatel JSC的工程师设计的。我们假设了将在三维配置中获得的墨滴大小分布函数与在二维配置中获得的分布函数联系起来的公式。伴随着这些，虽然在一般情况下，在这些配置中发现的喷雾半角似乎是相同的
