The precessing vortex core (PVC) is the dominant coherent structure of swirling jets, which
are commonly applied in gas turbine combustion. It stems from a global hydrodynamic …

Global stability and control of swirling jets and flames

UA Qadri - 2014 - repository.cam.ac.uk
Large-scale unsteady flow structures play an influential role in the dynamics of many
practical flows, such as those found in gas turbine combustion chambers. This thesis is …

Open-loop control of a global instability in a swirling jet by harmonic forcing: A weakly nonlinear analysis

CS Skene, UA Qadri, PJ Schmid - Physical Review Fluids, 2020 - APS
Highly swirling flows are often prone to precessing instabilities, with an azimuthal wave
number of m=− 1. We carry out a weakly nonlinear analysis to determine the response …

Effect of large disturbances on the local behavior of nonlinear physically interconnected systems

H Mangesius - IFAC Proceedings Volumes, 2013 - Elsevier
Abstract Systems that are physically interconnected, eg electric power systems, evolve in the
regime of physical consistency laws, such as balance of power flows. This complicates the …
