The comparison between different Reynolds numbers and cylinder arrangements shows time periodic responses for all cases at low Reynolds numbers, whereas the response is quasi-periodic at larger Reynolds numbers for two and three body cases. Furthermore, in the multi-body cases at higher Reynolds numbers, the fundamental frequencies for the involved singular bodies are identified, as well as new fundamental frequencies that seem to be associated with the system response as a whole entity. date_type: published date: 2018 event_title: AIAA SciTech Forum2018 .
