Multiscale interaction analysis of Landfall Typhoon Lekima (2019) based on vorticity equation diagnosis

open access: yesTropical Cyclone Research and Review
To investigate the multiscale interaction characteristics of Landfall Typhoon Lekima (2019), this study analyzed the characteristics of the different scale vortex structure and interactions among different scales based on vorticity equation diagnosis ...

Defining coherent vortices objectively from the vorticity [PDF]

open access: yesJournal of Fluid Mechanics, 2016
Rotationally coherent Lagrangian vortices are formed by tubes of deforming fluid elements that complete equal bulk material rotation relative to the mean rotation of the deforming fluid volume. We show that the initial positions of such tubes coincide with tubular level surfaces of the Lagrangian-averaged vorticity deviation (LAVD), the trajectory ...

Upper Ocean Thermodynamic Response to Coupling Currents to Wind Stress over the Gulf Stream

open access: yesJournal of Marine Science and Engineering
We use high-resolution coupled atmosphere–ocean model simulations over the Gulf Stream extension region during a winter season to examine the upper ocean thermodynamic response to including current feedback to atmospheric wind stress. We demonstrate that

Vorticity measurement in vortical flow.

open access: yesJOURNAL OF THE FLOW VISUALIZATION SOCIETY OF JAPAN, 1987
Computer-aided vorticity measuring system based on hotwire anemometry has been developed and used for investigation of time-dependent vortical flow field of a traveling vortex ring. The vorticity distributions obtained are visualized on computer graphics and are recorded as animation film.

Vorticity‐Driven µ‐Platelet Rotation and Selective Packing for Vertical Thermal–Electrical Interconnects

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.

Influence of Superhydrophobic Coatings on Turbulence and Vortical Structures in a Submerged Impinging Jet

open access: yesNanomaterials
The impact of liquid jets on solid surfaces is a critical hydrodynamic mechanism in applications like cooling and cleaning. Surface properties, particularly superhydrophobicity, can significantly alter flow development throughout the impingement process.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

open access: yesAdvanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Hyperon Production in Bi + Bi Collisions at the Nuclotron-Based Ion Collider Facility and Angular Dependence of Hyperon Spin Polarization

open access: yesParticles
The strange baryon production in Bi + Bi collisions at sNN=9.0 GeV is studied using the PHSD transport model. Hyperon and anti-hyperon yields, transverse momentum spectra, and rapidity spectra are calculated, and their centrality dependence and the ...
