Distribution Of Electric Field

Nanofibers were prepared in large quantities using a modified bubble-electro-spinning, where the distribution of electric field played an important role, and its distribution was studied numerically using 3-D Maxwell equation and verified experimentally. The results showed the increase of electric field strength could decrease the nanofiber diameter and enhance the nanofiber production.

Distribution Of Electric Field

In this paper, coupling field model of wind-sand-electricity around transmission line is built to solve mechanism of discharge of transmission line in sandstorm. The model is used to simulated distribution of electric field of transmission line in the condition of strong sand storm happened in Atushi City at March 12, 2006. In the sand-wind-electric field of the transmission line, the peak of electric field strength exceeds the discharge inception. It is considered that corona phenomenon occurs in the sandstorm, which is shown that the proposed method is of efficiency and practicality.

Parameter Values

Lane formation dynamics in externally driven pair-ion plasma (PIP) particles is studied in the presence of external magnetic field using Langevin dynamics (LD) simulation. The phase diagram obtained distinguishing the no-lane and lane states is systematically determined from a study of various Coulomb coupling parameter values. A peculiar lane formation-disintegration parameter space is identified; lane formation area extended to a wide range of Coulomb coupling parameter values is observed before disappearing to a mixed phase. The different phases are identified by calculating the order parameter. This and the critical parameters are calculated directly from LD simulation. The critical electric field strength value above which the lanes are formed distinctly is obtained, and it is observed that in the presence of the external magnetic field, the PIP system requires a higher value of the electric field strength to enter into the lane formation state than that in the absence of the magnetic field. We further find out the critical value of electric field frequency beyond which the system exhibits a transition back to the disordered state and this critical frequency is found as an increasing function of the electric field strength in the presence of an external magnetic field. The movement of the lanes is also observed in a direction perpendicular to that of the applied electric and magnetic field directions, which reveals the existence of the electric field drift in the system under study. We also use an oblique force field as the external driving force, both in the presence and absence of the external magnetic field. The application of this oblique force changes the orientation of the lane structures for different applied oblique angle values.
