چکیده

Corona discharges exist in a variety of forms (streamer and diffuse, steady and pulsed) and have multi-scale nature (in both space and time). High spatial resolution is required to analyze ionization fronts, streamers and Trichel pulses observed in corona discharges. We present multi-dimensional simulations of corona and glow discharges with adaptive Cartesian mesh using fluid models. Effects of physical model on spatial structure of discharges are discussed.

Simulations of Low-temperature Plasmas with Adaptive Cartesian Mesh

Many problems of gas discharge physics are characterized by the presence of large gradients of plasma parameters in localized domains (streamers, filaments, ionization fronts, etc). For such problems, the ability to dynamically adapt the mesh resolution to local plasma properties can substantially increase the accuracy and efficiency of simulations. This paper describes a new tool for plasma si...

Towards adaptive kinetic-fluid simulations of weakly ionized plasmas

This paper describes an Adaptive Mesh and Algorithm Refinement (AMAR) methodology for multi-scale simulations of gas flows and the challenges associated with extending this methodology for simulations of weakly ionized plasmas. The AMAR method combines Adaptive Mesh Refinement (AMR) with automatic selection of kinetic or continuum solvers in different parts of computational domains. We first re...

Immersed Boundary Method for Boltzmann and Navier- Stokes Solvers with Adaptive Cartesian Mesh

Adaptive Cartesian mesh methods have demonstrated unique abilities for automated mesh generation and dynamic mesh adaptation to flow solution and moving boundaries. However Navier-Stokes (NS) solvers with Cartesian mesh often produce large fluctuations of surface quantities (pressure, skin friction, and heat flux) at solid boundaries. We show that the Immersed Boundary Method (IBM) with adaptiv...

Current Distribution of Ac Surface Discharges and Associated Chemistry

It is shown that ac discharges propagating at an air / dielectric interface, though of planar structure, behave, till a critical voltage Vcrit, as corona discharges in an air gap, with similar propagation fields for the filamentary discharge components and similar glow components. This leads to consider the surface discharges as gas discharges propagating above the dielectric surface. Beyond Vc...
