Numerical Simulation on the Flow Pattern of a Gas-Liquid Two-Phase Swirl Flow. [PDF]
ACS Omega, 2022 The gas–liquid contact area can be increased by the gas–liquid swirl flow, and the heat and mass transfer efficiency between gas and liquid can be enhanced by the gas–liquid swirl flow. The gas hydrate formation can be promoted by the swirl flow.

The three-dimensional structure of swirl-switching in bent pipe flow [PDF]
Journal of Fluid Mechanics, 2017 Swirl-switching is a low-frequency oscillatory phenomenon which affects the Dean vortices in bent pipes and may cause fatigue in piping systems. Despite thirty years worth of research, the mechanism that causes these oscillations and the frequencies that

An experimental investigation of droplet morphology in swirl flow [PDF]
Journal of Fluid Mechanics, 2022 The interaction of a droplet with a swirling airstream is investigated experimentally using shadowgraphy and particle image velocimetry techniques. In swirl flow, the droplet experiences oppose-flow, cross-flow and co-flow conditions depending on its ...
