Stability and sensitivity analysis of the secondary instability in the sphere wake

V Citro, L Siconolfi, D Fabre, F Giannetti, P Luchini - Aiaa Journal, 2017 - arc.aiaa.org
The three-dimensional flow past a fixed sphere placed within a uniform stream is
investigated. This paper focuses on the second bifurcation, which is responsible for the …
