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.

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）功能表面上流动，在自然界、工程和精密制造业中无处不在。在这个泵启动项目中，研究人员用于分析此类问题的世界领先软件算法将被修改，以利用大规模并行高性能计算（HPC）架构和资源。这将有助于首次对实际表面上的流动进行计算，从而使预测能力的基本限制，例如液滴扩散和凝聚的时间尺度上的预测能力得到研究和量化。对这类重要流动问题的物理见解将对从事涂层工艺基础和液滴运动领域工作的学术研究人员、从事各种领域工作的工程师和科学家（如用于医疗诊断的微电子元件和微流体装置的生产）以及那些对开发更可持续的化学农药替代品感兴趣的人都有普遍的好处。
