Adjoint-based swirling flow injection control in a model combustion chamber: A numerical study
In the present work, an adjoint-based flow control strategy to suppress the precessing vortex core (PVC) in a swirl-stabilized model combustion chamber was studied. A global linear stability analysis of the mean flow yielded a marginally stable mode with azimuthal wavenumber m=1, accounting for the PVC oscillations. Th...
