Non-linearities in the thermoacoustic response of a premixed swirl burner [PDF]
, 2009 PhDLean premixed combustion remains one of the simplest and most effective methods of reducing NOx emissions in industrial gas turbines. Lean premixed flames are however prone to an undesirable side effect known as combustion instability, reducing ...

Investigation of the influence of swirl on a confined coannular swirl jet [PDF]
, 2010 Large Eddy Simulations are used to model a turbulent confined coannular combustor and examine the effects of swirl on the flow field and mixing. Three separate simulations with relatively high mesh resolutions and different swirl numbers have been ...

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 ...

Flow and combustion in disc and pent-roof SI engines [PDF]
, 2006 Reported in this thesis is a study of combustion in a disc-shaped combustion chamber spark ignition engine, and in-cylinder flow and combustion in an idealised pent-roof spark ignition engine. Both engines were skip fired, to remove residuals and ensure

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.

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.

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 ...
