Suppression of oscillatory fluid forces in cylinder wake: Optimal jet control position designed through resolvent analysis
The flow around a circular cylinder is a typical case of unstable separated flow, and
controlling its stability has long been a focus of flow control research. This study proposes an …

Triglobal resolvent-analysis-based control of separated flows around low-aspect-ratio wings
JHM Ribeiro, K Taira - arXiv preprint arXiv:2402.12553, 2024 - arxiv.org
We perform direct numerical simulations (DNS) of actively controlled laminar separated
wakes around low-aspect-ratio wings with two primary goals:(i) reducing the size of the …
