Key Points

The research aims to analyze the origins of vorticity in viscous separated flows over immersed bodies using back-in-time analysis.
Utilized the adjoint-vorticity framework for analysis.
Examined steady and unsteady separation in fluid flows over a sphere and prolate spheroid.
Considered boundary contributions of vorticity and its flux across different Reynolds numbers.
Identified wall flux contributions leading to axisymmetric separation at Re=200.
Unsteady separation at Re=300 demonstrated tracing of vorticity within the wake hairpin vortex.
Findings challenge classical descriptions, highlighting distinctions in vorticity origins between two- and three-dimensional flows.

We only have this paper's title and publication details.
