Swirl-Bypass Nozzle for CO2 Two-Phase Ejectors: Numerical Design Exploration
Energies, 2022 In this work, a novel ejector design concept of a swirl-bypass nozzle is proposed to improve off-design performance of CO2 two-phase ejectors. The swirl-bypass nozzle allows part of the flow to bypass into the ejector mixing chamber to generate swirl ...

On vortex/wave interactions. Part 2. Originating from axisymmetric flow with swirl [PDF]
, 2006 Following the study in Part 1 of cross-flow and other non-symmetric effects on vortex/wave interactions in boundary layers, the present Part 2 applies the ideas of Part 1 and related works to an incident axisymmetric flow supplemented by a small swirl or

Simulation of the Internal Flow of the High-Pressure Swirl Injector
Journal of Thermal Science and Technology, 2009 The simulation of the internal flow of a kind of high-pressure swirl injector was carried out with multiphase and cavitation models basing on the movement mesh. The spray was also simulated with the result of the internal flow simulation.

Preliminary numerical study of single bubble dynamics in swirl flow using volume of fluid method
Nuclear Engineering and Technology, 2021 Spacer grid with mixing vane had been widely used in nuclear reactor core. One of the main feather of spacer grid with mixing vane was that strong swirl flow was formed after the spacer grid.

A deformable microswimmer in a swirl: capturing and scattering dynamics [PDF]
, 2014 Inspired by the classical Kepler and Rutherford problem, we investigate an analogous set-up in the context of active microswimmers: the behavior of a deformable microswimmer in a swirl flow. First we identify new steady bound states in the swirl flow and

Effect of pre-swirl on gas–liquid two-phase flow characteristics in a helical axial-flow pump [PDF]
AIP AdvancesIn helical axial-flow pumps for gas–liquid multiphase transport, unsteady flow induced by the interaction between the trailing edge of the guide vanes and the impeller inlet often deteriorates the hydraulic performance.

The Effect of Inlet Swirl on the Rotordynamic Shroud Forces in a Centrifugal Pump [PDF]
, 1992 The role played by fluid forces in determining the rotordynamic stability of a centrifugal pump is gaining increasing attention. The present research investigates the contributions to the rotordynamic forces from the discharge-to-suction leakage flows ...

On Flow Reversal in Turbulent Swirling Flow
Journal of the Physical Society of Japan, 2003 Summary: A turbulent swirling flow is studied with the aid of a variational method. The mean-flow field is expressed by the mean vorticity proportional to its curl. The total axial flux and total helicity per unit length are introduced to characterize the swirling flow, and the condition for the reversal of the axial flow near the center of flow is ...

Effect of Swirl on Rotordynamic Forces Caused by Front Shroud Pump Leakage [PDF]
, 2002 Unsteady forces generated by fluid flow through the impeller shroud leakage path of a centrifugal pump were investigated. The effect of leakage path inlet swirl (pump discharge swirl) on the rotordynamic forces was re-examined.
