Symmetry and states of self stress in triangulated toroidal frames

Electromagnetic effects on toroidal momentum transport

A parametric study of electromagnetic effects on toroidal momentum transport has been performed. The work is based on a new version of the Weiland model where symmetry breaking toroidicity effects derived from the stress tensor have been taken into account. The model includes a self-consistent calculation of the toroidal momentum diffusivity, which contains both diagonal and off-diagonal contri...

Topological Symmetry Breaking of Self–interacting Fractional Klein–gordon Field on Toroidal Spacetime

Quartic self–interacting fractional Klein–Gordon scalar massive and massless field theories on toroidal spacetime are studied. The effective potential and topologically generated mass are determined using zeta function regularization technique. Renormalization of these quantities are derived. Conditions for symmetry breaking are obtained analytically. Simulations are carried out to illustrate r...

Comparison of the Eccentricity Faults Effects on the Performance of several Toroidal Wounded Axial Flux Permanent Magnet Motors

Eccentricity fault is one the most common fault types of disk-type permanent magnet machines, which could lead to devastating effects. Unfortunately, most of the previous works have studied this fault and its detection techniques for slotted structure with common winding. Therefore, in this paper, the effects of eccentricity faults on the performance of single-sided slotted, single-sided slotle...

Toroidal Momentum Confinement in Tokamaks

Theories for the toroidal momentum confinement in tokamaks have been developed. It is shown that the logarithmic gradient of the toroidal flow is a linear combination of logarithmic gradients of the plasma pressure and the temperature in neoclassical quasilinear theory. The fluctuation-induced toroidal stress consists of a diffusion flux, a convective flux, and a residual flux. The effects of a...
