Electric field control of three-dimensional vortex states ...

Both ferromagnetic and ferroelectric vortex states are attractive candidates for advanced three-dimensional (3D) architecture of RAM units with high storage density, low-power, and high operation speed. But in the case of ferromagnets, potential applications of vortex states are typically discussed for thin-film elements rather than spherical nanoparticles. A further difference is the characteristic length scale given by the width of uncharged Ising-Bloch domain walls in inorganic ...

Three-dimensional simulation of vortex shedding flow in ...

Three-dimensional vortex shedding flow occurs at Re=500 for an isolated cylinder with zero yaw angle. Secondly, the effect of the yaw angle on the vortex shedding suppression is one of the aims of this study, which is stronger at this relative low Reynolds number than at higher Reynolds numbers. Finally, a relatively low Reynolds number allows the direct numerical simulations (DNS) to be conducted at an affordable computational time.

Three-dimensional vortex structures under breaking waves ...

The large-scale vortex structures under spilling and plunging breakers are investigated, using a fully three-dimensional large-eddy simulation (LES). When an overturning jet projecting from the crest in a breaking wave rebounds from the water surface ahead, the vorticity becomes unstable in a saddle region of strain between the rebounding jet and a primary spanwise vortex, resulting in spanwise undulations of the vorticity. The undulations are amplified on a braid in this saddle region ...

Three-dimensional quasi-geostrophic vortex equilibria with ...

We investigate arrays of $m$ three-dimensional, unit-Burger-number, quasi-geostrophic vortices in mutual equilibrium whose centroids lie on a horizontal circular ring; or $m+1$ vortices where the additional vortex lies on the vertical ‘central’ axis passing through the centre of the array. We first analyse the linear stability of circular point vortex arrays. Three distinct categories of vortex arrays are considered. In the first category, the

Collective modes in three-dimensional magnonic vortex crystals

Three different types of arrangements have been investigated. They are shown in Fig. 1(a).

The disks have a diameter of and a thickness of 40 nm for type 1 and 30 nm for type 2 and 3.

A vortex ring impinging on a three-dimensional circular cylinder is studied using large eddy simulation for a Reynolds number Re4 10=×4 based on the initial translational speed and diameter of the vortex ring. We have investigated the evolution of vortical structures and identified three typical evolution phases. When the primary vortex approaches the cylinder closely, a

This is a good way to identify coherent vortices less dependent on the magnitude of the vorticity ...

While vortex rings have also been predicted to exist in ferromagnets [5], they have not yet been observed. Using X-ray magnetic nanotomography [6], we imaged three-dimensional structures forming closed loops in a bulk micromagnet, each composed of a vortex-antivortex pair. Based on the magnetic vorticity, a quantity analogous to hydrodynamic vorticity, we identify these configurations as ...

Three-dimensional vortex breakdown in swirling jets and wakes 333 in any sense a direct consequence of instability. This view is supported by the experimental fact that under carefully controlled conditions a purely axisymmetric form of breakdown occurs both in tube-and-vane and closed container experiments. Since it is generally agreed that vortex flows are much more stable to axisymmetric ...

Locomotor forces on a swimming fish: three-dimensional ...

Velocity fields quantified in three perpendicular planes in the wake of the fins allowed three-dimensional reconstruction of downstream vortex structures. At low swimming speed (0.5 L s(−)(1)), vorticity is shed by each fin during the downstroke and stroke reversal to generate discrete, roughly symmetrical, vortex rings of near-uniform circulation with a central jet of high-velocity flow. At ...

This paper proposes a three-dimensional vortex method for a gas-particle two-phase compound round jet.

In order to discuss the validity of the method, an air jet, loaded with small glass particles, issuing from a ...

This paper describes the results of a flow visualization study which concerns three-dimensional vortex structures in a leading-edge separation bubble formed along the sides of a blunt flat plate. Dye and hydrogen bubbles were used as tracers. Reynolds number (Re), based on the plate thickness, was varied from 80 to 800. For 80 < Re < 320, the separated shear layer remains laminar up to the ...

The polarization pattern is controlled by self-organized state formation 24 ...

Three-dimensional space - Wikipedia

Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point). This is the informal meaning of the term dimension.

Vorticity - Wikipedia

In a three-dimensional flow, vorticity (as measured by the volume integral of the square of its magnitude) can be intensified when a vortex line is extended — a phenomenon known as vortex stretching. This phenomenon occurs in the formation of a bathtub vortex in outflowing water, and the build-up of a tornado by rising air currents.

Three-dimensional longitudinal vortices are considered in the context of the leading-edge vortex flow generated on the lee-side of a highly swept wing with sharp leading edges. Experiments were conducted in a low speed water flow such that the wing chord Reynolds number was between 10,000 and 62,000. The development of the leading-edge vortex flow is described in terms of the evolution of the ...

In this paper, we extend the notion of Eulerian indicators (EIs), previously developed for two dimensional time dependent flows, to three dimensional time dependent flows, where the time dependence can be arbitrary. These are applied to a study of transport and mixing in the Hill’s spherical vortex subject to a linear strain rate field. We consider the axisymmetric case and the fully three ...

We study three-dimensional vortex lattice structures in purely dipolar Bose-Einstein condensate (BEC). By using the mean-field approximation, we obtain a stability diagram for the vortex states in purely dipolar BECs as a function of harmonic trap aspect ratio (λ) and dipole-dipole interaction strength (D) under rotation. Rotating the condensate within the unstable region leads to collapse ...
