Numerical simulation of temperature fields during the sublimationgrowth of SiC single crystals, using WIAS-HiTNIHS
We present numerical computations of the temperature fields in axisymmetric growth apparatus for sublimation growth of silicon carbide (SiC) bulk single crystals by physical vapor transport (PVT) (modified Lely method). ...
Transient numerical study of temperature gradients during sublimationgrowth of SiC
Dependence on apparatus design
Using transient and stationary mathematical heat transfer models including heat conduction, radiation, and radio frequency (RF) induction heating, we numerically investigate the time evolution of temperature gradients in ...
Adaptive Step-Size Control in Simulation of Diffusive CVD Processes
We present control strategies of a diffusion process for chemical vapor deposition for metallic bipolar plates. In the models, we discuss the application of different models to simulate the plasma-transport of chemical ...
Higher-Order Splitting Method for Elastic Wave Propagation
Motivated by seismological problems, we have studied a fourth-order split scheme for the elastic wave equation. We split in the spatial directions and obtain locally one-dimensional systems to be solved. We have analyzed ...
Overlapping Schwarz wave form relaxation for the solutionof coupled and decoupled system of convectiondiffusion reaction equation
In this article we study the convergence and the error bound for the solution of the convection diffusion reaction equation using overlapping Schwarz wave form relaxation method combined with the first order fractional ...
Linear and Quasi-Linear Iterative Splitting Methods
Theory and Applications
In this paper we consider time-decomposition methods and present interesting model problems as benchmark problems in order to study the numerical analysis of the proposed methods. For the time-decomposition methods we ...
Fourth-Order Splitting Methods for Time-DependantDifferential Equations
This study was suggested by previous work on the simulation of evolution equations with scale-dependent processes, e.g., wave-propagation or heat-transfer, that are modeled by wave equations or heat equations. Here, we ...
Macro- and Microsimulations for a SublimationGrowth of SiC Single Crystals
The numerous technical applications in electronic and optoelectronic devices, such as lasers, diodes, and sensors, demand high-quality silicon carbide (SiC) bulk single crystal for industrial applications. We consider an ...
Error estimates for finite volume element methodsfor convection–diffusion–reaction equations
In this paper, we study finite volume element (FVE) method for convection–diffusion–reaction equations in a two-dimensional convex polygonal domain. These types of equations arise in the modeling of a waste scenario of a ...
