GRK 2462: Processes in natural and technical Particle-Fluid-Systems (PintPFS)

土壤是天然的颗粒-流体系统（PFS），其中发生了复杂的物理、化学和生物过程、界面过程和相变，这些过程还没有得到充分的实验研究，没有得到很好的理解，也不能以足够的精度进行数值模拟。在技术pfs中，粒子的某些特性是通过受控的物理、化学和生物过程、界面过程和相变（如功能化粒子）产生的。技术PFS还需要进一步的研究，包括理解、建模和工艺优化。自然PFS和技术PFS的问题部分相似。因此，很明显，为了达到科学发现的好处，研究自然和技术PFS跨学科的过程。正是在这一点上，可以看出计划研究训练组的原创性和潜力。各个学科相同或不同地命名、建模和模拟类似的过程。特别是在实验研究的长度尺度上，PFS的模型和模拟是不同的。通过与战略合作伙伴和TUHH的设备（如电子显微镜）的合作，这些过程在几个长度尺度上被可视化。过程模型和数值模拟方法有助于更好地理解和描述复杂过程。通过合作和跨学科的研究方法，有望有新的发现。研究培训小组为实现这些目标提供了最佳框架。土木工程、机械工程和过程工程学科的科学家将把他们的研究重点放在指导主题“自然和技术颗粒流体系统过程”（PintPFS）内。相关科学家在PFS的实验研究、建模和模拟方面的现有能力和资源使跨学科研究方法成为可能，从而提高了对以下领域创新的期望：PFS建模的进展，对毛细管效应的更好理解，侵蚀、运输和沉积过程的建模，功能化颗粒的发展，以及PFS数值实验的发展。该培训小组得到了访问科学家和战略合作伙伴的支持，特别是汉堡的德国电子同步加速器（DESY）和亥姆霍兹技术中心（HZG）。论文项目采用跨学科的研究方法。为了达到这些目标，研究培训小组为奖学金获得者提供结构化的资格和监督概念，支持在不同的研究主题中快速定位，加速工作流程，与现有研究结构建立联系，并获得社交技能。

Soils are natural particle-fluid systems (PFS), in which complex physical, chemical and biological processes,interfacial processes, and phase transitions occur, that are not sufficiently investigated experimentally,well-understood, and that cannot be simulated numerically with sufficient accuracy yet. In technicalPFS certain properties of particles are generated by means of controlled physical, chemical and biologicalprocesses, interfacial processes, and phase transitions (e. g. functionalized particles). Technical PFS alsorequire further research regarding understanding, modelling and process optimization. The problems innatural and technical PFS are partly analogous. Therefore, it is obvious, to investigate processes innatural and technical PFS interdisciplinary in order to reach a benefit of scientific findings. Exactly in thispoint, the originary and the potential of the planned research training group can be seen. The individualdisciplines name, model, and simulate similar processes identically or differently. Especially the lengthscales, on which PFS are investigated experimentally, modelled and simulated are different. By meansof the cooperation with strategical partners and the facilities at TUHH, e. g. electron microscopy, theprocesses are visualized over several length scales. Process models and numerical simulation methods ofthe involved collegiates serve for better understanding and description of complex processes. By means ofthe cooperation and interdisciplinary methodology new findings are expected. A research training groupprovides an optimal framework to reach these objectives. Scientists of the disciplines civil engineering,mechanical engineering and process engineering will focus their research within the guiding topic ”Processesin natural and technical Particle-Fluid Systems“ (PintPFS). Existing competences and resourcesof the involved scientists regarding experimental investigations, modelling and simulation of PFS enablean interdisciplinary research approach that raises expectation of innovations in the following fields:progress in modelling of PFS, better understanding of capillary effects, modelling of erosion, transportand sedimentation processes, development of functionalized particles, as well as development of numericalexperiments for PFS. The training group is supported by visiting scientists and strategical partners,especially Deutsches Elektronen-Synchrotron (DESY) at Hamburg and Helmholtz-Zentrum Geesthacht(HZG). The proposed dissertation projects show the interdisciplinary research approach. To reach theobjectives, the research training group is accompanied by structured qualification and supervision conceptsfor the scholarship holders supporting a fast orientation within the different research topics, anacceleration of work processes, a networking with existing research structures, and the acquisition ofsocial skills.
