The purpose of the proposed research is to realise the burgeoning potential of exciting mesoscopic and multiscale modelling techniques to address industrially and fundamentally important fluid flow problems that have hitherto eluded all attempts at practically useful, predictive modelling. The primary focus is on the forced wetting of 'real' solid surfaces, i.e. those exhibiting roughness, porosity and/or chemical heterogeneity - a class of flows that is enormously important in the coating and printing industries, among many other applications. The vision for the proposed project is to address current obstacles to the successful application of mesoscopic modelling to such flows, and thereby to deliver a fundamental change in process modelling capabilities, permitting for the first time the accurate prediction of the influences of given surface morphologies and properties on the performance of the wetting process, and the impact upon the end product. Success in this project will also lead to a better understanding of the capabilities of mesoscopic modelling, yielding benefits in a wide range of applications, from microfluidic devices to enhanced oil recovery and carbon dioxide sequestration, and providing the means to perform detailed proof-of-concept simulations for new technologies.

拟议研究的目的是实现激动人心的介观和多尺度建模技术的蓬勃发展的潜力，以解决工业上和根本上重要的流体流动问题，这些问题迄今未能在实际有用的预测建模方面进行所有尝试。主要的焦点是“真实”固体表面的强制润湿，即那些表现出粗糙度、孔隙率和/或化学异质性的表面--这类流动在涂料和印刷行业以及许多其他应用中非常重要。拟议项目的愿景是解决目前将介观模拟成功应用于此类流动的障碍，从而从根本上改变过程模拟能力，首次能够准确预测给定表面形貌和性质对润湿过程性能的影响以及对最终产品的影响。该项目的成功还将使人们更好地了解介观模拟的能力，在从微流控装置到提高石油采收率和二氧化碳封存等广泛应用中产生好处，并为新技术提供进行详细概念验证模拟的手段。
