Book Synopsis Powerful Pulsed Plasma Generators by : Victor Kolikov
Download or read book Powerful Pulsed Plasma Generators written by Victor Kolikov and published by Springer. This book was released on 2018-07-25 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents experimental and theoretical results on extremely powerful plasma generators. It addresses pulsed electrical mega-ampere arcs and the mechanisms of energy transfer from the arc into hydrogen, helium and air under pressures up to 250 MPa and currents up to 2 MA. Extreme plasma parameters and increased energy density in the arc were achieved. It was found experimentally that increasing the initial gas pressure to hundreds of MPa leads to improved arc stability, high efficiency of energy transfer from arc to gas, and plasma enthalpy growth. The data obtained data provides the basis for the development of electrophysical devices with high energy density, e.g. high intensity sources for visible, UV and X-ray irradiation for laser pumping, generators of high enthalpy plasma jets, and plasma chemical reactors.

Book Synopsis Pulsed Plasma Generator Development and Low-temperature Plasma-assisted Combustion at Atmospheric Pressure by : Mathew Evans
Download or read book Pulsed Plasma Generator Development and Low-temperature Plasma-assisted Combustion at Atmospheric Pressure written by Mathew Evans and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis presents an experimental study of the engineering and physics of high-voltage nanosecond-pulsed diffuse discharges, and their application to the enhancement of lean-premixed combustion at atmospheric pressure. The technology development in this work is focused on providing appropriate low-temperature radical pools, and the experiments are aimed at demonstrating the effect of these pools for combustion actuation. The experimental results are focused on the explanation of the physical processes associated with these discharges. The discharge propagation and emission spectrum were examined, the distribution functions of particles along internal energy levels were calculated, and the resulting enhancement of combustion was observed. This work shows that the plasma emission from fuel-lean mixtures is primarily composed of high vibrational populations of electronically excited nitrogen molecules, upon which a low-temperature is measured on the rotational manifold. Previous work shows that these low-temperature excited particles will collide with molecular oxygen, or fuel molecules, to produce species (atomic/molecular ground/excited oxygen, fragmented fuel molecules...) that accelerate chain-branching reactions in the combustion reaction mechanism. This work shows that the majority of the electronically excited vibrational states of nitrogen molecules, in a diffuse discharge, decay rapidly after the application of a high-voltage pulse. These findings set the framework for the implementation of diffuse plasma to laboratory-scale combustion enhancement. As an integral part of this work, the design and development of electrical generators that can produce such a reactive medium in large volume is included, and extensively detailed. An inexpensive solid-state pulse generator, based on commercially available amorphous ferromagnetic materials, is designed and developed to drive capacitive loads. The generator is used to produce large volumes of diffuse plasma and increase the blow off velocity of stagnation flames. To further investigate this enhancement, an optically accessible plasma burner is implemented and used for the detailed study of stagnation flame plasma actuation. This work shows that significant actuation can be provided to a flame, when diffuse plasma is placed upstream, and directly in contact with the combustion front. The displacement of the leading edge of a flame, into the fresh unburned mixture, is measured following a high-voltage actuating pulse. The displacement of the leading edge strongly points toward low-temperature reactivity enhancement. The optical and electrical characteristics of the diffuse plasma are reported for both the non-combusting and combusting flows. These provide a more accurate picture of the thermal characteristics and complex phenomena occurring in this transient discharge. Streamer propagation dynamics and coupled energy measurements are reported to provide further insight regarding the delicate balance that exists between plasma and flame sheet in this experimental configuration. It can be concluded that diffuse plasma is an effective low-temperature chemical actuation method for combustion enhancement at atmospheric pressure.To conclude this work, the first step toward high-pressure actuation of combustion with diffuse plasma was explored. The task of producing diffuse plasma above atmospheric pressure was undertaken. This work presents the development of a second solid-state pulse generator with increased power delivery capabilities. The generator is used to produce large volumes of diffuse plasma in a high-pressure vessel filled with air. It is found that diffuse plasma actuation could eventually be implemented in a high-pressure combustion experiment using this technology." --

Book Synopsis Control and Nonlinear Dynamics on Energy Conversion Systems by : Herbert Ho-Ching Iu
Download or read book Control and Nonlinear Dynamics on Energy Conversion Systems written by Herbert Ho-Ching Iu and published by MDPI. This book was released on 2019-07-01 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ever-increasing need for higher efficiency, smaller size, and lower cost make the analysis, understanding, and design of energy conversion systems extremely important, interesting, and even imperative. One of the most neglected features in the study of such systems is the effect of the inherent nonlinearities on the stability of the system. Due to these nonlinearities, these devices may exhibit undesirable and complex dynamics, which are the focus of many researchers. Even though a lot of research has taken place in this area during the last 20 years, it is still an active research topic for mainstream power engineers. This research has demonstrated that these systems can become unstable with a direct result in increased losses, extra subharmonics, and even uncontrollability/unobservability. The detailed study of these systems can help in the design of smaller, lighter, and less expensive converters that are particularly important in emerging areas of research like electric vehicles, smart grids, renewable energy sources, and others. The aim of this Special Issue is to cover control and nonlinear aspects of instabilities in different energy conversion systems: theoretical, analysis modelling, and practical solutions for such emerging applications. In this Special Issue, we present novel research works in different areas of the control and nonlinear dynamics of energy conversion systems.
