VπLES splits the flow structures into large scale ones, resolved on the grid (Eulerian approach), and small scale ones, represented by vortex particles (Lagrangian approach). Two transport equations for grid and particle solution are derived which are dynamically coupled through the existence of coupling terms in each of them. The method resembles LES with an effort to directly reproduce the subgrid motion at least in the statistical sense.<eng> vorgelegt von Sina Samarbakhsh GutachterInnen: Nikolai Kornev (Lehrstuhl für Modellierung und Simulation (LeMoS), Universität Rostock) ; Suad Jakirlic (Institute of Fluid Mechanics and Aerodynamics, Technical University of Darmstadt) Dissertation Universität Rostock 2022 620 620.1064 620 http://purl.uni-rostock.de/rosdok/id00003970 https://doi.org/10.18453/rosdok_id00003970 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00003970-1 https://d-nb.info/1293538868/34 Development and validation of hybrid grid-based and grid-free computational VπLES method--(DE-627)1819759407 urn:nbn:de:gbv:28-rosdok_id00003970-1 doi: 10.18453/rosdok_id00003970 oclc: 1346646925 ppn: (DE-627)1818073161
