Computational Modelling of Leidenfrost Fractals

莱登弗罗斯特效应通过强大的蒸发通量将微小的液滴悬浮在热的表面上，当水滴在热锅上滑行时可以看到。了解这种情况何时发生对于众多技术的效率至关重要，包括我们在诺基亚贝尔实验室的合作者正在开发的下一代电子产品的喷雾冷却。贝尔大学的实验最近揭示了与直觉相反的接触动力学，表明在撞击液滴的情况下，表面的分形润湿与纳米尺度的蒸汽流竞争。这个项目将使用非传统的数学建模和计算技术，结合贝尔大学的理论驱动的定向实验，获得对这一现象的前所未有的洞察。

The Leidenfrost effect levitates small liquid drops above hot surfaces via a strong evaporative flux and is seen when water droplets skate across a hot pan. Understanding when this occurs is critical for the efficiency of numerous technologies, including the spray-cooling of next-generation electronics that our collaborators at Nokia Bell Labs are developing. Experiments at Bell have recently revealed counter-intuitive contact dynamics that display fractal surface wetting in competition with the nanoscale vapour flow under impacting droplets. This project will use unconventional mathematical modelling combined with computational techniques to gain unprecedented insight into this phenomenon combined with theory-driven targeted experiments at Bell.
