The accurate computation of thin film flows and the motion of droplets on real functional surfaces.

流体在包含微尺度地形和/或化学异质性的真实(人造和自然发生的)功能表面上的流动在整个自然、工程和精密制造行业中普遍存在。在这个泵启动项目中，研究人员用于分析这类问题的世界领先的软件算法将被修改，以利用大规模并行高性能计算(HPC)架构和资源。这将有助于首次进行真实表面上的流动计算，使预测能力的基本极限得以调查和量化。对这类重要流动问题的物理洞察将对从事涂层工艺基础和液滴运动领域的学术研究人员、从事不同领域工作的工程师和科学家以及那些对开发更可持续的化学农药替代品感兴趣的人具有普遍意义。

Fluid flow over real (man-made and naturally occurring) functional surfaces containing micro-scale topographic and/or chemical heterogeneities are ubiquitous throughout nature, engineering and the precision manufacturing industries. During this pump-priming project, the investigators' world leading software algorithms for analysing such problems will be modified to exploit massively parallel High Performance Computing (HPC) architectures and resources. This will facilitate the computation of flows over realistic surfaces to be carried out for the first time, enabling the fundamental limits of predictive capabilities, such as those on the time-scales of droplet spreading and coalescence, to be investigated and quantified.The physical insight gained into this important class of flow problems will be of generic benefit both to academic researchers, working in the fields of coating process fundamentals and droplet motion, to engineers and scientists working in diverse fields such as in the production of micro-electronic components and microfluidic devices for medical diagnostics, and to those interested in developing more sustainable alternatives to chemical pesticides.
