The article analyses the degree of water superheating with respect to the liquid-vapour equilibrium line in experiments on the micro-explosion of a composite droplet comprised of two immiscible liquids. The analyses were carried out for water-in-fuel drops under conditions of high-power heating. This degree is compared with the mechanical effect of droplet decay, involving the formation of daughter droplets. Our attention was drawn to the smallness of the degree of superheating preceding the decay. A model of the boiling up of such a droplet is constructed taking into account the sources of premature boiling up of water inherent in micro-explosive experiments. The dependencies of the boiling up temperature of water on the heating rate obtained in the model turned out to be in accordance with the experimental data across a wide range of heating rates. A hypothesis about the local superheating of the transition layer, which is not detected in the experiment, is formulated. Thus, a step has been taken to clarify the essence of the mismatch of the degree of superheating of water recorded by macroscopic equipment along with a completely satisfactory generation of daughter droplets serving as the basis for advanced fuel technology.

高功率加热下的复合液体：燃料中水滴微爆炸中水的过热


该文章分析了由两种不混溶液体组成的复合液滴微爆炸实验中水相对于液-汽平衡线的过热程度。对高功率加热条件下燃料中的水滴进行了分析。该程度与液滴衰变的机械效应进行比较，涉及子液滴的形成。我们的注意力被衰变前的过热度很小所吸引。考虑到微爆炸实验中固有的水过早沸腾的来源，构建了这种液滴沸腾的模型。模型中获得的水沸腾温度对加热速率的依赖性与大范围加热速率的实验数据一致。提出了有关实验中未检测到的过渡层局部过热的假设。因此，已经采取了一步来澄清宏观设备记录的水过热度不匹配的本质，以及完全令人满意的子液滴生成，作为先进燃料技术的基础。
