Electric potential near a wall in plasma with magnetic field increasing toward a wall is investigated analytically. A magnetic field that is symmetric about an axis and increases monotonically toward the wall is considered. The potential profile is analyzed by solving the plasma-sheath equation that gives the electric potential in the plasma region and the sheath region near the wall self-consi...

Thermal end effects on electroosmotic flow in a capillary are numerically investigated in this paper. The model accounts for the dynamic coupling effects of Joule heating on the temperature field, the electrical double layer field, the applied electric potential field and the flow field in the full capillary from reservoir to reservoir. These fields are strongly coupled via temperature dependen...

Abstract: In this study, using density functional theory and the SIESTA computationalcode, we investigate the electronic and optical properties of the armchair graphenenanoribbons and the armchair boron nitride nanoribbons of width 25 in the presence of atransverse external electric field. We have observed that in the absence of the electricfield, these structures are se...

Current profile control is employed in the Madison Symmetric Torus @R. N. Dexter et al., Fusion Technol. 19, 131 ~1991!# reversed field pinch to reduce the magnetic fluctuations responsible for anomalous transport. An inductive poloidal electric-field pulse is applied in the sense to flatten the parallel current profile, reducing the dynamo fluctuation amplitude required to sustain the equilibr...

in this paper, the effect of electric field on two-dimensional low reynolds air flow around an airfoil and variation of the forces acting on the airfoil is numerically investigated. the electric current and poisson’s equations are solved and the outcome is considered as a source term in the momentum equations. the energy equation is not considered due to its weak effect on the phenomena. the fi...

We have studied the multipole polarizability of a graded spherical particle in a nonuniform electric field, in which the conductivity can vary radially inside the particle. The main objective of this work is to access the effects of multipole interactions at small interparticle separations, which can be important in non-dilute suspensions of functionally graded materials. The nonuniform electri...

The concept of the de Hoffmann–Teller frame is revisited for a high Mach-number quasi-perpendicular collisionless shock wave. Particle-in-cell simulation shows that the local magnetic field oscillations in the shock layer introduce a residual motional electric field in the de Hoffmann– Teller frame, which is misleading in that one may interpret that electrons were not accelerated but decelerate...
