Development of circular cylinder blade wind turbine driven by longitudinal vortex
It is known that the longitudinal vortex alternately and periodically forms diagonally backward of the upstream cylinder of the cruciform system consisted of the upstream cylinder and the downstream strip-plate and causes the strong periodic lift force ...

In a circular cylinder blade wind turbine driven by a longitudinal vortex, the torque characteristics of the turbine are greatly affected by the flow field at the blade tip. In general, wind turbines reduce drag by making the blade tips thinner. However,

Spin-2 Bose–Einstein condensates in an annular trap with spin–orbit coupling
We study the ground-state phases of spin–orbit coupled spin-2 Bose–Einstein condensates in a two-dimensional concentrically coupled annular trap with the attractive and repulsive spin-exchange interactions, respectively.

Making ghost vortices visible in two-component Bose-Einstein condensates
Ghost vortices constitute an elusive class of topological excitations in quantum fluids since the relevant phase singularities fall within regions where the superfluid density is almost zero.

Unveiling nonequilibrium dynamics of solitonic and topological defect structures in a multidimensional nonlinear medium is a current frontier across diverse fields. One of the quintessential objects is a ring dark soliton (RDS), whose dynamics are expected to display remarkable interplay between symmetry and self-patterned topological defect formation ...

In earlier works by the present authors, it was shown that a large cross-flow excitation is induced to a circular cylinder by setting another cylinder downstream in a cruciform arrangement with a certain gap between them, caused by longitudinal vortices ...

Earlier wind tunnel experiments supported by visualization in water flow carried out by the present authors showed that two types of longitudinal vortices shed periodically from a cruciform two identical circular cylinder system in uniform flow.

Thermal striping caused by the mixing of fluids at different temperatures is one of the most important issues in the design of Sodium cooled Fast Reactors (SFRs), because it may cause high-cycle thermal fatigue in the structure and affect the structural ...
