DEM simulation of 3D structure formation by the deposition of charged nanoparticles in electric fields

As part of the doctoral programme "Self-organized multifunctional structures for adaptive high-performance lightweight construction" at the Functional Materials Campus of Clausthal University of Technology, this project uses numerical methods to investigate the structural composition of electrically charged particles on surfaces. The basis for the calculations is the Discrete Element Method (DEM), which has established itself in recent years as a universal tool for modeling the transport and interaction of particles. The method makes it possible to investigate the influence of electric fields on the transport and deposition of particles. As part of the doctoral program, morphological studies on the deposition of electrically charged nanoparticles depending on external electric fields, aerodynamic forces, etc. are to be carried out following further methodological developments. This includes the transport of charge in the deposited layer. The planned calculations are very computationally intensive, which is why the computers of the North German Network for High Performance Computing (HLRN) will probably be used. This subproject will be carried out in close cooperation with project 4 in the doctoral program (Electrodynamically controlled assembly of 3D structures from functional nanoparticles) and project 5 (Analytical calculation of 2D and 3D structures of maximum entropy and new material modifications).
