Available in PDF, EPUB and Kindle. Book excerpt: Plasma models have regions of validity that depend on local parameters.In some problems a computationally expensive, high-fidelity model is required in a small subset of the domain while lower-cost reduced models can adequately describe the plasma behavior everywhere else. The goal of this research is to investigate methods for spatially coupling the various plasma models such that the simplest plasma model that is locally valid can maintain global physical fidelity while improving computational efficiency. This research has two primary components. The first component is investigating numerical methods which can efficiently couple the various plasma models. Mixed implicit-explicit (ImEx) temporal solution schemes are investigated to produce schemes which are numerically stable when the time scales of interest span several orders of magnitude, and the physics of interest is dominated by long time scale physics. The spatial discretization method of choice is based on the discontinuous Galerkin (DG) method. Traditional DG methods are capable of producing numerical schemes with high spatial accuracy, but produce large and stiff implicit systems. To address this deficiency, the traditional DG scheme is augmented with a hybridized discontinuous Galerkin (HDG) scheme which is specifically designed to handle implicit temporal schemes. The second component of this research is investigating methods for making the plasma model dynamically (re-)decomposed based on local plasma conditions to produce an adaptive scheme. These metrics can be derived by examining the mathematical differences between the plasma models. This approach allows the determination of relative scale on which non-charge-neutral effects are significant, as well as which metrics are dependent on local gradients or purely on local conditions. Key metrics comparing the MHD and two-fluid models include examining charge neutrality, two-temperature effects, Hall effects, and finite-electron-mass effects.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers the reader an overview of the basic approaches to the theoretical description of low-temperature plasmas, covering numerical methods, mathematical models and modeling techniques. The main methods of calculating the cross sections of plasma particle interaction and the solution of the kinetic Boltzmann equation for determining the transport coefficients of the plasma are also presented. The results of calculations of thermodynamic properties, transport coefficients, the equilibrium particle-interaction cross sections and two-temperature plasmas are also discussed. Later chapters consider applications, and the results of simulation and calculation of plasma parameters in induction and arc plasma torches are presented. The complex physical processes in high-frequency plasmas and arc plasmas, the internal and external parameters of plasma torches, near-electrode processes, heat transfer, the flow of solid particles in plasmas and other phenomena are considered. The book is intended for professionals involved in the theoretical study of low-temperature plasmas and the design of plasma torches, and will be useful for advanced students in related areas.
Download or read book Modeling and Design of a Physical Vapor Deposition Process Assisted by Thermal Plasma PS PVD written by Dmitrii Ivchenko and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma Spray Physical Vapor Deposition (PS-PVD) aims to substantially evaporate material in powder form by means of a DC plasma jet to produce coatings with various microstructures built by vapor condensation and/or by deposition of nanoclusters. In the conventional PS-PVD process, all the material treatment takes place in a medium vacuum atmosphere, limiting the evaporation process or requiring very high-power torches. In the present work, an extension of conventional PS-PVD process as a two-chamber process is proposed and investigated by means of numerical modeling: the powder is vaporized in a high pressure chamber (105 Pa) connected to the low pressure (100 or 1,000 Pa) deposition chamber by an expansion nozzle, allowing more energetically efficient evaporation of coarse YSZ powders using relatively low power plasma torches. Expansion nozzle erosion and clogging can obstruct the feasibility of such a system. In the present work, through the use of computational fluid dynamics, kinetic nucleation theory and cluster growth equations it is shown through careful adjustment of system dimensions and operating parameters both problems can be avoided or minimized. Divergence angle of the expansion nozzle is optimized to decrease the clogging risk and to reach the most uniform coating and spray characteristics using the aforementioned approaches linked with a DSMC model of the rarefied plasma gas flow. Results show that for 100 Pa, the thermal barrier coating would be mainly built from vapor deposition unlike 1,000 Pa for which it is mainly built by cluster deposition.
