Scale bridging simulation of dynamic wetting based on the phase field method (B07)

B 07 N的目的是对复杂基底上多尺度动态润湿过程中接触线处的局部输运过程的基本理解。将使用基于扩散界面相场法并在OpenFOAM中开发的专有CFD求解器。该方法能够描述在多孔/结构化基材中的吸胀和渗透过程，特别是在毛细作用主导的润湿过程中。重点在于准确检测局部的异质性（孔径分布，粗糙度，功能化），以及在规模桥接方法，要实现现代HPC技术相结合，DG方法和混合原子连续方法。

The aim of B07N is the fundamental understanding of local transport processes at the contact line in multiscale, dynamic wetting processes on complex substrates. A proprietary CFD-solver based on the diffuse-interface phase field method and developed in OpenFOAM will be used. The method enables the description of imbibition and penetration processes in porous/structured substrates, especially during capillarity dominated wetting. Focus lies on the exact detection of local heterogeneities (pore size distribution, rough-ness, functionalization) as well as on a scale bridging methodology, to be realized by combining modern HPC techniques, DG methods and the hybrid atomistic-continuum method.
