Abstract:
In this paper, we studied the method of electrets electrode which formed to accumulate negative electric charge by corona discharge. The breakdown voltage sample and damaged sample by various corona discharges have made material stabilization and improved characteristics of electric charge storage throughout the annealing process. After the experiment made material stabilization nearly melting point by many kinds of annealing conditions, we did the corona discharge again by the charged high voltage, a discharge electrode gap, and a discharged time. As we compared it with the best condition, we confirmed that characteristics of electric charge storage were improved.

Abstract:
The magnetically enhanced negative- and positive-corona discharges were compared in the current study. In the magnetically enhanced corona discharges, some small permanent magnets were employed to form the local magnetic fields on the corona discharge region, in which the Larmor movements of free electrons enhance ionizations of the gas molecules. The characteristics of discharge current changing in the magnetically enhanced corona discharges were firstly revealed here. The experimental results showed that the relative increases of corona discharge currents had a maximum value in both the magnetically enhanced negative- and positive-corona discharges, when a magnetic field was fixed and the inter-electrode voltages were changed. The reasons for the maximum values were analyzed in detail. In addition, comparing with the magnetically enhanced positive-corona discharge, the inter-electrode voltage for the maximum value is lower for the negative one, because the intensity of inter-electrode electric field was altered by the accumulations of positive or negative ions.

Abstract:
Abstract Because of the low normal atmospheric pressure and frequent, more severe corona discharges in high-altitude regions. The electromagnetic environment problems caused by the corona discharge restrict the line design in high-altitude areas. The variance in the law of negative DC corona characteristics under different air pressure conditions is derived using an artificial climate tank with adjustable air pressure. The characteristics of the negative DC needle-plate corona discharge were measured experimentally. The negative DC corona discharge pulses at 89.4 kPa–56.04 kPa were obtained, and the characteristics of the current pulses were statistically examined. The study of the mechanism of the DC corona discharge can benefit from the research findings as essential reference data.

Abstract:
Corona discharge is a kind of self maintained discharges that occurs in the extremely uneven electric field which often happens in the industrial and daily living environments. In this paper, we study the characteristics of corona discharge, especially the ones in the time domain and frequency domain of negative corona discharge. Based on the analyzed characteristics mentioned above, we design and optimize a kind of patch antennas, which has the advantages of small volume compared to the traditional one used to receive the signals generated by corona discharge. This new antenna can be used in the field of security inspection on high voltage transmission lines applied in the industrial applications.

Abstract:
The working gas of discharge-pumped excimer lasers is generally a mixture of rare gases and monohalide. Typically, the working gas is preconized to generate reproducible uniform glow discharge. In high-power (more than 100 W) excimer lasers, this pre-ionization is achieved through spark discharge in the discharge chamber. In this study, a high-power discharge-pumped XeCl* excimer laser with corona preionisation was designed to investigate the feasibility of applying corona preionisation in high-power excimer lasers as well as analyse the correlation of corona discharges characteristics with laser discharge properties. The electron avalanche triggered by ultraviolet preionisation in the laser was numerically studied by creating 2D models. The simulation results revealed that the additional ionisation induced by the secondary electron emission of the cathode together with the dielectric constant of the corona bars significantly affect the discharge current of the principal electrodes. Under the condition of the design values, the peak preionisation electron density between electrodes was approximately 108 cm−3, and the laser discharge was quite uniform, which theoretically proved the feasibility of using corona preionisation instead of spark discharge preionisation in high-power practical devices.

Abstract:
The goal of this work was to assess the feasibility of using corona discharge quenching by anesthetic gases as a technique for anesthetic gas concentration measurement. Two experiments were conducted to investigate corona discharge and measure changes due to anesthetic gases. Experiment One used a chamber in which a high voltage was imposed across two parallel plane electrodes, between which gases under test could flow. Halothane, ethrane, and nitrous oxide were shown to have corona discharge quenching effects proportional to their relative potency. In an attempt to improve accuracy and decrease baseline drift a second system was fabricated. This system used an improved voltage source, temperature and humidity control and a chamber in which gases flowed between two concentric cylindrical electrodes. Results from the second experiment showed that the complex physics of corona discharge quenching by anesthetic gases could not be easily used for reliable measurement of anesthetic gas concentrations.

Abstract:
Carbon dioxide mitigation technologies have garnered increasing attention over the past decade to prevent further detrimental effect to the environment and increased global warming. Non-thermal plasma technology, specifically corona discharge, is a technology that is capable of reducing CO2 to CO which can then be utilised as a feedstock for various chemical feedstocks. As there is no existing work on this specific discharge type, a new reactor and experimental method was developed in order to assess its viability as a CO2 splitting technology. Additionally, a numerical model was built to validate the experimental results. This thesis investigates pulsed power corona discharges for the splitting of CO2 and its ad-mixtures with argon and nitrogen. Special attention is paid to the conversion percentage and the energy efficiency of this process. Few previous works have examined the use of pulsed power in plasma applications and thus there is little understanding of the mechanisms and kinetically pathway of CO2 reduction in this type of system. this thesis aims to propose what they may be and how it differs from other plasma technology. The results indicate that pulsed power corona discharges offer superior energy efficiency compared to other technologies however, the conversion is somewhat lower than other reported works. It is theorised that the input voltage waveform plays a significant role in determining the kinetical pathway of CO2 reduction and future work should revolve around optimising the voltage waveform to maximise both the conversion and energy efficiency. Argon and nitrogen both have a positive effect on CO2 conversion and efficiency, up to a point, yet further addition sees more energy directed towards reactions and energy transfer to these species instead of the desired reaction of CO2 to CO.

Abstract:
Corona on electrified conductors (power lines, transmission lines, and antennas) is a significant source of electromagnetic interference to aircraft. When corona occurs in radio frequency equipment, it usually signals the failure of the system to operate as designed. The Townsend integral, which describes breakdown in low-frequency non-uniform fields, was derived from the electron continuity equation. Predictions of corona onset were developed using new formulas for net ionization. Measurements of 60 Hz corona onset for an isolated cylindrical monopole were compared with these predictions. A corona onset criterion, which describes breakdown in non-uniform radio frequency (RF) fields, was also derived from the electron continuity equation. Measurements of corona onset at 300 MHz for the same isolated cylindrical monopole were compared with predictions. The results confirm that the derived breakdown criteria are good predictors of corona onset at both 60 Hz and 300 MHz for cylindrical geometries in the range 0:1 rp 10:0 cm torr. A discussion of the transition frequency between power frequency and high frequency corona onset is included. The argument is made that corona onset criteria developed for cylindrical geometries are useful for any geometry where the local electric field strength can be characterized.

Full text
Abstract:
To enhance the bondability of polyetheretherketone (PEEK), surface treatment techniques of plasma and corona discharge have been evaluated. The results have shown that these two methods are effective and practical. The treated materials not only reach their highest possible joint strength, but also show very promising joint durability. In addition, the various environments, e. g. atmosphere, heat, water, and solvent, have little effects on the enhanced bondability of the treated materials. By using Contact Angle Measurement, Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS) and Time of Flight Secondaty Ion Mass Spectrometry (TOF-SIMS) to characterise the PEEK surfaces before and after treatment, it was established that the lack of active chemical groups, which if present can form strong interatomic and intermolecular forces across the adhesive/PEEK interface, is the main cause for the poor bondability of the untreated PEEK. Both plasma and corona discharge treatment introduce such active functional groups, for instance, hydroxyl, carboxylic acid, amine and etc., onto the surface of PEEK film and so greatly enhance the intrinsic adhesion at the interface between treated PEEK surfaces and epoxy adhesive, as confirmed by the TOF-SIMS interfacial analysis. It is deduced that low molecular weight molecules (LMWM) are formed on treated surfaces, which contain high concentration of oxygen and/or nitrogen, and can be removed by solvent washing. The removal of LMWM will drastically reduce the wettability of the treated surfaces, but does not impair the enhanced bondability. It has been found that both plasma and corona discharge treated surfaces are in a thermodynamically unstable state. When exposed to the atmosphere, the treated surfaces tend to lose their improved wettability and decrease their surface polarity. Increasing temperature can not only accelerate these processes but also change the surface chemical structures of the treated materials back to that of the untreated films to some extent, as revealed by the TOF-SIMS analysis. Water immersion, on the contrary, tend to reverse the above processes.

Abstract:
Electrohydrodynamics (EHD) is a promising research field with several trending applications. Even though the phenomenon was first observed centuries ago, there is very little research until the middle 20th century, as the mechanisms behind it were very poorly understood. To this date, the majority of research is based on the development of empirical models and the presentation of laboratory experiments. This work begins with an extensive literature review on the phenomenon, clarifying conflicts between researchers throughout the history and listing the findings of the latest research. The literature review reveals that there are very few mathematical models describing even the most important parameters of the EHD fluid flow and most are either empirical or greatly simplified. As such, practical mathematical models for the assessment of all primary performance characteristics describing EHD fluid accelerators (Voltage Potential, Electric Field Intensity, Corona Discharge Current and Fluid Velocity) were developed and are begin presented in this work. These cover all configurations where the emitter faces a plane or another identical electrode and has a cylindrical surface. For configurations where the emitter faces a plane or another identical electrode and has a spherical surface, Corona Discharge Current and Fluid Velocity models have been presented as well. Laboratory experiments and computer simulations were performed and are being thoroughly presented in Chapter 4, verifying the accuracy and usability of the developed mathematical models. The laboratory experiments were performed using two of the most popular EHD electrode configurations - wire-plane and needle-grid. Finally, the findings of this research are being summarized in the conclusion, alongside with suggestions for future research. The step-by-step development of the equipotential lines mathematical model is presented in Appendix A. Appendix B covers the mathematical proof that the proposed field lines model is accurate and that the arcs are perpendicular to the surface of the electrodes and to all of the equipotential lines.

Abstract:
Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters. Capacitor banks are widely used in the modern electrical transmission system in order to improve power quality and efficiency. In other words, this device aims to be involved in harmonic disturbance elimination, improve the power factor (PF), provide voltage control and stability which leads into more sustainable energy systems. Utilizing high voltage components, such as shunt capacitors in the power grid can introduce new challenges. One of these challenges is known as corona discharge. The aim of the presented master thesis is to study and develop corona discharge suppression models on high voltage capacitor banks which is implemented in collaboration with ABB power grids, Sweden. The main concerns are, effective factors on corona emergence, corona inception voltage levels, and corona suppression methods. Also, this study evaluates the verification of existing suppression. Two various approaches were applied and compared. The aim of the first approach is to evaluate corona discharge by electric field calculations on three various capacitor banks with different voltage levels. The simulation was implemented based on Maxwell’s equations and finite element method (FEM) by utilizing COMSOL Multiphysics software. The second approach is based on streamer inception and propagation. The calculation on this method is fulfilled with the help of MATLAB software. The results of both approaches were found reasonably compatible. It is discovered that corona discharge can appear in different voltage levels on capacitor banks based on various factors, such as the geometry of the bank. Consequently, the suppression method may vary case by case and different proposals were suggested in order to optimize the corona suppression rings.
På grund av den allmänna betydande befolknings- och ekonomiska tillväxttakten har kraven på energi ökat markant under det senaste decenniet. Detta innebär att integrationen av förnybara energier i elnätet har eskalerat samt begäran om reaktiv effektkompensering, spänningsstabilitet och mildring av harmoniska filter. kondensatorbatterier används ofta i det moderna elektriska transmissionssystemet för att förbättra strömkvaliteten och effektiviteten. Med andra ord syftar denna enhet till att vara involverad i eliminering av harmonisk störning, förbättra effektfaktorn (PF), tillhandahålla spänningskontroll och stabilitet som leder till mer hållbara energisystem. Att använda högspänningskomponenter, som shuntkondensatorer i elnätet, kan skapa nya utmaningar. En av dessa utmaningar kallas korona-urladdning. Syftet med den presenterade masteruppsatsen är att studera och utveckla korona-urladdningsmodeller på högspännings-kondensatorbatterier som implementeras i samarbete med ABB Power Grids, Sverige. De viktigaste problemen är effektiva faktorer för korona uppkomst, spänningsnivåer korona och metoder för att underlätta korona. Dessutom utvärderar denna studie verifieringen av befintliga undertryckningsmetoder. Två olika tillvägagångssätt tillämpades och jämfördes. Syftet med det första tillvägagångssättet är att utvärdera korona-urladdning genom elektriska fältberäkningar på tre olika kondensatorbatterier med olika spänningsnivåer. Simuleringen implementerades baserat på Maxwells ekvationer och finita elementmetoden (FEM) genom att använda COMSOL Multiphysics programvara. Det andra tillvägagångssättet är baserat på strömningslinjernas början och utbredning. Beräkningen av denna metod genomförs med hjälp av MATLAB-programvaran. Resultaten från båda metoderna tycktes vara rimligt kompatibla. Det upptäcks att korona-urladdning kan förekomma i olika spänningsnivåer på kondensatorbatterier baserat på olika faktorer, till exempel batteriets geometri. Följaktligen kan undertryckningsmetoden variera från fall till fall och olika förslag föreslogs för att optimera koronaundertryckningsringarna.

Abstract:
An ionic wind is formed when air ions generated by a corona discharge are accelerated by an electric field and exchange momentum with neutral air molecules, causing air flow. Because ionic winds can generate flow with no moving parts, they offer an attractive method for enhancing the heat transfer from a surface that would otherwise only be cooled by natural convection and/or radiation. In the presence of an external, flat plate flow, ionic winds distort the boundary layer such that local heat transfer is enhanced at the wall, and recent work has suggested that integrating such devices can be useful for cooling electronic components locally. In this work, corona discharges are generated between a steel wire and copper tape electrode pair on a flat plate, perpendicular to the bulk flow direction such that the discharge is in the direction of the bulk flow. The corona discharge current is characterized, and a corona glow and spark discharge are visualized. Experimental studies of the heat transfer from a heated flat plate are conducted using an infrared camera which indicated both upstream and downstream cooling along the entire length of the wire. Heat transfer coefficients are increased by more than 200% above those obtained from bulk flow alone and are correlated to the fourth root of the corona current. Preliminary parametric studies demonstrate the influence of the electrode-pair configuration on the cooling enhancement and suggest improved geometric designs.

Abstract:
The use of Corona (Transient Plasma) discharge as an ignition source alternative to spark ignition (SI) for a Natural Gas fired engine presents an opportunity for increased efficiency and reduced NOx emissions. The multiple ignition sites created by a Corona discharge produce a faster and more complete burn than conventional SI. Bench tests show a faster combustion rise time (∼3×) and higher peak combustion pressures with corona discharge compared to SI. There are challenges encountered in retrofitting a corona discharge ignition system onto an IC engine. Electrode design and placement are critical in preventing arc formation and engine knock.

Abstract:
Climate and hydrology are major drivers of ecosystems. They dramatically shape ecosystem structure and function, particularly in arid and semi-arid ecosystems. Understanding changes in climate, groundwater, and water quality and quantity is central to assessing the condition of park biota and key cultural resources. The Sonoran Desert Network collects data on climate, groundwater, and surface water at 11 National Park Service units in southern Arizona and New Mexico. This report provides an integrated look at climate, groundwater, and springs conditions at Chiricahua National Monument (NM), Coronado National Memorial (NMem), and Fort Bowie National Historic Site (NHS) during water year (WY) 2019 (October 2018–September 2019). Overall annual precipitation at Chiricahua NM and Coronado NMem in WY2019 was approximately the same as the normals for 1981–2010. (The weather station at Fort Bowie NHS had missing values on 275 days, so data were not presented for that park.) Fall and winter rains were greater than normal. The monsoon season was generally weaker than normal, but storm events related to Hurricane Lorena led to increased late-season rain in September. Mean monthly maximum temperatures were generally cooler than normal at Chiricahua, whereas mean monthly minimum temperatures were warmer than normal. Temperatures at Coronado were more variable relative to normal. The reconnaissance drought index (RDI) indicated that Chiricahua NM was slightly wetter than normal. (The WY2019 RDI could not be calculated for Coronado NMem due to missing data.) The five-year moving mean of annual precipitation showed both park units were experiencing a minor multi-year precipitation deficit relative to the 39-year average. Mean groundwater levels in WY2019 increased at Fort Bowie NHS, and at two of three wells monitored at Chiricahua NM, compared to WY2018. Levels in the third well at Chiricahua slightly decreased. By contrast, water levels declined in five of six wells at Coronado NMem over the same period, with the sixth well showing a slight increase over WY2018. Over the monitoring record (2007–present), groundwater levels at Chiricahua have been fairly stable, with seasonal variability likely caused by transpiration losses and recharge from runoff events in Bonita Creek. At Fort Bowie’s WSW-2, mean groundwater level was also relatively stable from 2004 to 2019, excluding temporary drops due to routine pumping. At Coronado, four of the six wells demonstrated increases (+0.30 to 11.65 ft) in water level compared to the earliest available measurements. Only WSW-2 and Baumkirchner #3 have shown net declines (-17.31 and -3.80 feet, respectively) at that park. Springs were monitored at nine sites in WY2019 (four sites at Chiricahua NM; three at Coronado NMem, and two at Fort Bowie NHS). Most springs had relatively few indications of anthropogenic or natural disturbance. Anthropogenic disturbance included modifications to flow, such as dams, berms, or spring boxes. Examples of natural disturbance included game trails, scat, or evidence of flooding. Crews observed 0–6 facultative/obligate wetland plant taxa and 0–3 invasive non-native species at each spring. Across the springs, crews observed six non-native plant species: common mullein (Verbascum thapsus), spiny sowthistle (Sonchus asper), common sowthistle (Sonchus oleraceus), Lehmann lovegrass (Eragrostis lehmanniana), rabbitsfoot grass (Polypogon monspeliensis), and red brome (Bromus rubens). Baseline data on water quality and water chemistry were collected at all nine sites. It is likely that that all nine springs had surface water for at least some part of WY2019, though temperature sensors failed at two sites. The seven sites with continuous sensor data had water present for most of the year. Discharge was measured at eight sites and ranged from < 1 L/minute to 16.5 L/minute.
