“…The electric field at the streamer head is within the 6.6 × 10 During the streamer propagation, the electric field at the streamer head increased first, attained its highest value at 4.5 ns, and reduced gradually. This trend was consistent with that in [66] where the point-to-plane gap is 1 mm.…”

Abstract:A numerical study has been conducted to understand the mutual effect among nearby needles in a multi-needle electrode dielectric barrier discharge. In the present paper, a fluid-hydrodynamic model is adopted. In this model, the mutual effect among nearby needles in a multi-needle configuration of an atmospheric air dielectric barrier discharge are investigated using a fluid-hydrodynamic model including the continuity equations for electrons and positive and negative ions coupled with Poisson's equation. The electric fields at the streamer head of the middle needle (MN) and the side needles (SNs) in a three-needle model decreased under the influence of the mutual effects of nearby needles compared with that in the single-needle model. In addition, from the same comparison, the average propagation velocities of the streamers from MN and SNs, the electron average energy profile of MN and SNs (including those in the streamer channel, at the streamer head, and in the unbridged gap), and the electron densities at the streamer head of the MN and SNs also decreased. The results obtained in the current paper agreed well with the experimental and simulation results in the literature.

“…Another efficient second-order numerical scheme was introduced by Van Leer (Van Leer, 1979) and named the second order Monotonic Upwind-Centered Scheme For Conservation Laws (MUSCL) scheme. This algorithm was used through the Finite Volume Method (FVM) in the 3D modelling of high pressure micro-discharges in micro-cavities (Eichwald et al, 1998) in the 1.5D (Eichwald et al, 2006) and the 2D (Ducasse et al, 2007) modelling of the positive streamer propagation. At the beginning of the century (2000) a new approach to gas discharge modelling was presented in the works of Georghiou et al (Georghiou et al, 1999(Georghiou et al, , 2000 and Min et al (Min et al, 2000 in which they used the Finite Element Method (FEM) to solve the electro-hydrodynamic model for parallel plate and wire-plate gaps.…”

“…In the frame work of the microdischarge modelling, the obtained results (the streamer morphology and velocity, the production of charged and radical particles, the dissipated power) depend on the hydrodynamics physical model (Eichwald et al, 2006;Li et al, 2007) the discretisation method (Finite Difference Method: FDM, Finite Element Method: FEM, or Finite Volume Method: FVM) and the numerical solver used (Ducasse et al, 2007Soria-Hoyo et al, 2008). Indeed, the solution of the micro-discharge fluid models requires high resolution numerical schemes in order to be able to consider the strong coupling between both the transport and field equations and the steep gradients of the charged particles evolution in a sharp and very fast ionizing wave (Soria-Hoyo et al, 2008).…”

“…The initial attempts of integrating this continuity equation were carried out by Davies et al in the 1960s using the first-order method-of-characteristics (MOC) [2]. To address its drawback of limited resolution, Davies developed a second-order accurate method of characteristics [3]. Actual numerical integration of the continuity equations was carried out by Morrow and Lowke [1].…”

Abstract-Insulation degradation is the primary reason for aging and eventual failure of electrical equipment. Any measurement that forewarns an impending breakdown of the equipment can be a boon to asset managers. Partial discharge (PD) is one such phenomenon that can be monitored for assessing the quality of insulation. However, the phenomenon of PD is quite intricate and requires an understanding of various concurrent processes. In this paper, some of the methods used to simulate this complex event have been reviewed. At the fundamental level, PD is a localized breakdown that occurs without complete bridging of the insulation. These are feeble and extremely fast, nanosecond discharges. They can be thought of as motion of charges under the influence of an external electric field, which has exceeded the breakdown strength in a small region of the insulation. When such discharges occur in voids in solid insulation, they generate signals in the electrical, chemical and acoustic domains. Also, PD causes physical damage due to bombardment of these charged particles on the walls of the void. The charges are generated by ionization of the gas filled in the void. Once ionized, the motion of these particles is governed not only by the external field, but also by the space charge so created. There are various methods that can be used to simulate the motion of these charges. Of these, particle-in-cell (PIC) method can be applied in a Lagrangian frame of reference, where the particles retain their identity, and their trajectories are monitored by calculating the force on them. This force is determined by the field at their location. This method is fairly intuitive. The other class, Eulerian, treats the charges as a density distribution and then determines its motion. In this, the flux-corrected transport (FCT) scheme basically considers the motion as governed by the charge continuity equations coupled with the Poisson's equation. The continuity equations also account for the generation of the charges, due to ionization, and their possible subsequent recombination or attachment. However, these events, as recorded, are also statistical in nature, and the effect of previous discharges on the subsequent ones can hardly be ignored. The method of including these in the simulation has also been reviewed.
