The overall objective of this work is to improve the resolution of concentrated vortices. This work focuses on grid based, grid free methods and coupled methods to capture the details of vortices especially further downstream after the vortex has rolled up and started to decay. The work focuses on a hybrid method as a coupling of grid based and grid free vortex method.<eng> vorgelegt von Mahesh Dhone GutachterInnen: Nikolai Kornev (Universität Rostock, Lehrstuhl für Modellierung und Simulation) ; Uwe Ritschel (Universität Rostock, Lehrstuhl für Windenergietechnik) Dissertation Universität Rostock 2020 620 620.1064 620 SK 950 UF 4300 31.76 33.06 50.33 http://purl.uni-rostock.de/rosdok/id00002635 https://doi.org/10.18453/rosdok_id00002635 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002635-3 https://d-nb.info/1293659207/34 Resolution of Tip Vortices by grid-based, grid-free and coupled methods using CFD--(DE-627)1691738859 urn:nbn:de:gbv:28-rosdok_id00002635-3 doi: 10.18453/rosdok_id00002635 oclc: 1142963004 ppn: (DE-627)1691542474
