The hydrodynamic instabilities in the flow field of a swirl-stabilized combustor are
investigated theoretically. These instabilities give rise to large-scale flow structures that …

The swirling flow exiting the runner of a hydraulic turbine is further decelerated in the
discharge cone of the draft tube to convert the excess of dynamic pressure into static …

Coherent structures in the far field of a round turbulent jet are investigated experimentally
and modelled by local linear stability analysis (LSA) and local resolvent analysis (RA). The …

A precessing vortex core (PVC) is a self-excited helical instability that results from the
precession of the vortex core around the flow axis in the upstream region of a vortex …

In this paper we propose a framework for orthogonal decomposition of swirling flows applied
to problems originating from turbomachines, where dynamics of the swirling flow in the draft …

In this study, three-dimensional flow structures at a Reynolds number of 16 000 are
measured by stereoscopic particle image velocimetry to reveal the dynamic structures of a …
