Investigation of Vector Discretization Schemes for Box Volume Methods

چکیده
The application of the box integration method in Technology CAD environments is investigated. A particular difficulty arises from physical models like the impact ionization rate or the high-field mobility within the drift-diffusion carrier transport equations which rely on vector quantities. We discuss different methods how generation rates can be approximated in the box scheme and how the requirements for the applied vector discretizations are. Simulation results of devices operated near break-down are presented using implementations of the presented schemes. Advantages and disadvantages in respect to implementation, to errors, and to convergence behavior are presented.

On the Comparison of Evolution Galerkin and Discontinuous Galerkin Schemes
The aim of this paper is to compare some recent numerical schemes for solving hyperbolic conservation laws. We consider the flux vector splitting finite volume methods, finite volume evolution Galerkin scheme as well as the discontinuous Galerkin scheme. All schemes are constructed using time explicit discretization. We present results of numerical experiments for the shallow water equations fo...
متن کاملImplementation and Critical Investigation on Modulation Schemes of Three Phase Impedance Source Inverter
New control circuits and algorithms are frequently proposed to control the impedance (Z) source inverter in efficient way with added benefits. As a result, several modified control techniques have been proposed in recent years. Although these techniques are clearly superior to the simple boost control method which was initially proposed along with the Z-source inverter (ZSI), little or conf...
متن کاملNumerical Investigation on Compressible Flow Characteristics in Axial Compressors Using a Multi Block Finite Volume Scheme
An unsteady two-dimensional numerical investigation was performed on the viscous flow passing through a multi-blade cascade. A Cartesian finite-volume approach was employed and it was linked to Van-Leer's and Roe's flux splitting schemes to evaluate inviscid flux terms. To prevent the oscillatory behavior of numerical results and to increase the accuracy, Monotonic Upstream Scheme for Conservat...

We introduce a time-implicite Voronoi box based finite volume discretization for the initial-boundary value problem of a scalar nonlinear viscous conservation law in a one, twoor threedimensional domain. Using notations from the theory of explicit finite volume methods for hyperbolic problems and results from the Perron-Frobenius theory of nonnegative matrices, we establish various existence, s...

In the present work, the Roe, the Steger and Warming, the Van Leer, the Harten, the Frink, Parikh and Pirzadeh, the Liou and Steffen Jr. and the Radespiel and Kroll schemes are implemented, on a finite volume context and using an upwind and unstructured spatial discretization, to solve the Euler equations in the three-dimensional space. The Roe, the Harten, and the Frink, Parikh and Pirzadeh sc...
