Toroidal and poloidal energy in rotating Rayleigh–Bénard convection [PDF]
Journal of Fluid Mechanics, 2014 AbstractWe consider rotating Rayleigh–Bénard convection of a fluid with a Prandtl number of $\mathit{Pr}=0.8$ in a cylindrical cell with an aspect ratio ${\it\Gamma}=1/2$. Direct numerical simulations (DNS) were performed for the Rayleigh number range $10^{5}\leqslant \mathit{Ra}\leqslant 10^{9}$ and the inverse Rossby number range $0\leqslant 1 ...

Magnetorotational Explosions of Core-Collapse Supernovae
Acta Polytechnica CTU Proceedings, 2014 Core-collapse supernovae are accompanied by formation of neutron stars. The gravitation energy is transformed into the energy of the explosion, observed as SN II, SN Ib,c type supernovae.

Toroidal Vortices of Energy in Tightly Focused Second-Order Cylindrical Vector Beams
Photonics, 2021 In this paper, we simulate the focusing of a cylindrical vector beam (CVB) of second order, using the Richards–Wolf formula. Many papers have been published on focusing CVB, but they did not report on forming of the toroidal vortices of energy (TVE) near

Rotating bubble and toroidal nuclei and fragmentation [PDF]
Nuclear Physics A, 1996 The energy of rotating bubble and toroidal nuclei predicted to be formed in central heavy-ion collisions at intermediate energies is calculated within the generalized rotating liquid drop model. The potential barriers standing in these exotic deformation paths are compared with the three-dimensional and plane-fragmentation barriers.

Effect of negative triangularity on tearing mode stability in tokamak plasmas
Nuclear Fusion, 2023 The influence of negative triangularity (NT) of the plasma shape on the n = 1 (n is the toroidal mode number) tearing mode (TM) stability has been numerically investigated, with results compared to that of the positive triangularity (PT) counterpart.

A model for the reversal of the toroidal rotation in tokamak [PDF]
Nuclear Fusion, 2012 Abstract The transition from toroidal counter- to co-rotation in the core plasma has been observed at L to H transition in several tokamaks. Spontaneous reversal has also been observed in TCV beyond a threshold in the density. We develop a model based on the following phenomenology: (1) the increase in the gradient of the pressure ...

Manufacturing of Rotational Toroidal Shells in Coin Minting
EngA novel forming process was developed to create rotating elements in collector coins by shaping thin-walled tubes into toroidal shells in a single stage. This process introduces new aesthetic effects and functionalities to the coin market. By controlling

Dynamics of Threads Wrapping a Filament's Leg Prior to the Eruption on 2021 October 28
The Astrophysical Journal, 2023 Although the magnetic field structures of solar filaments have been studied for several decades, the detailed evolution of the structure around a filament prior to its eruption is rarely observed. On 2021 October 28 in AR 12887, a major solar flare (X1.0

Advanced Healthcare Materials, EarlyView.Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...
