A High-Order Discontinuous Galerkin Method for Modeling Micro-Pulsed Plasma Thrusters
نویسنده
چکیده
We present a new numerical method to model micro-pulsed plasma thrusters as a single -fluid/twotemperature plasma flow. A spectral/hp element spatial discretization is employed both for structured and unstructured meshes in twoand three-dimensions. This method is based on a discontinuous Galerkin treatment of the advection and diffusion components, and it is stable in the L2 sense. Preliminary simulations of MHD flow in two different geometries are presented, and p-refinement is demonstrated that allows higher order accuracy without re -meshing.

A Hybridized Crouziex-Raviart Nonconforming Finite Element and Discontinuous Galerkin Method for a Two-Phase Flow in the Porous Media
In this study, we present a numerical solution for the two-phase incompressible flow in the porous media under isothermal condition using a hybrid of the linear lower-order nonconforming finite element and the interior penalty discontinuous Galerkin (DG) method. This hybridization is developed for the first time in the two-phase modeling and considered as the main novelty of this research.The p...
متن کاملSolving elliptic eigenvalue problems on polygonal meshes using discontinuous Galerkin composite finite element methods
In this paper we introduce a discontinuous Galerkin method on polygonal meshes. This method arises from the Discontinuous Galerkin Composite Finite Element Method (DGFEM) for source problems on domains with micro-structures. In the context of the present paper, the flexibility of DGFEM is applied to handle polygonal meshes. We prove the a priori convergence of the method for both eigenvalues an...

This paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. The method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions. The construction of the nonstandard method is based on the special treatment of the interface using suitable jump conditio...

An integro-differential equation, modeling dynamic fractional order viscoelasticity, with a Mittag-Leffler type convolution kernel is considered. A discontinuous Galerkin method, based on piecewise constant polynomials is formulated for temporal semidiscretization of the problem. Stability estimates of the discrete problem are proved, that are used to prove optimal order a priori error estimate...
