The swirl was introduced upstream of the base corner by either spinning non-canted or non-spinning canted fins. Depending on the introduced swirl rate, both the experimental and numerical results show two distinctively different wake flow structures. The fluid-dynamic processes present in the rotating wakes and the resulting structural changes are analyzed in detail. 2021-02-12T11:44:13Z 2021-02-12T11:44:13Z 2021 book ONIX_20210212_9783731510307_9 https://library.oapen.org/handle/20.500.12657/46722 ger Schriftenreihe des Instituts fur Stromungsmechanik, Karlsruher Institut fur Technologie application/pdf Attribution-ShareAlike 4.0 International 978-3-7315-1030-7.pdf KIT Scientific Publishing 10.5445/KSP/1000118606 This study investigates the effects of swirl on the supersonic wake of longitudinally-aligned axisymmetric afterbodies.
