Swirling flows are of considerable practical importance. They are used for example to
increase heat transfer in pipes or to stabilize flames at a distance from the injector unit by …

This review addresses the current state of research into active control and suppression of
vortex rope in hydroturbines under off-design operating conditions. Only active control …

We report on experimental study of flow and pressure pulsations in draft-tube of a laboratory
air model of Francis-99 hydro-turbine operating over a broad range of regimes employing a …

An experimental investigation of the cavitating turbulent flow in a simplified hydraulic turbine
was carried out to examine flow features in a wide range of speed and discharge conditions …

In this paper, we investigate the flow structures and pressure fields of a free annular swirling
jet flow undergoing vortex breakdown. The flow field is analyzed by means of time-resolved …

An axial-flow vane-type bubble separator for TMSR with regard to its working principle and
separation efficiency was investigated experimentally and numerically. Experiments study …

This paper presents the results of a parametric experimental study of free swirling flow at the
exit of a flat-vane axial swirler. A total of 16 data sets were acquired by combining four …

A finite-volume solver is used to compute the cyclonic motion in a vortex chamber assuming
steady, incompressible, and inviscid flow conditions. A parametric campaign enables us to …

This paper presents an experimental study of a strongly swirling turbulent flow with the
formation of a precessing vortex core (PVC) that emerges at the outlet of a tangential swirler …

This paper presents the effect of the conical diffuser angle (θ= 0°, 2°, 4°) on the Precessing
Vortex Core (PVC) induced in confined swirling airflows generated by axial swirlers with two …
