This article proposes a combustion method based on the combination of nonequilibrium plasma generated by medium barrier discharge and water additives. The influence of different H2O atomization rates on discharge power, mass loss, and temperature variation during plasma-assisted coal combustion processes was investigated. The research findings indicate that, under a fixed power supply voltage amplitude of 13.5 kV, as the H2O atomization rate increases from 0 to 3.0 mL/min, the asymmetry of discharge current increases while discharge power decreases. When the H2O atomization rate is 1.2 mL/min, the mass loss, temperature, and combustion surface reach their maximum values. Excessive H2O inhibits coal combustion. Compared with the case of no H2O addition, at a power supply voltage amplitude of 13.5 kV and a H2O atomization rate of 1.2 mL/min, the combustion rate of coal significantly increases, and the combustion limit is extended.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"669-677"},"PeriodicalIF":1.3,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is unknown that how these wake formations impact technologies, such as touchless potential sensing and the electrostatic tractor. Therefore, wakes are generated in the Electrostatic Charging Laboratory for Interactions between Plasma and Spacecraft (ECLIPS) vacuum chamber at the University of Colorado at Boulder to determine how to account for and take advantage of the wake formations. The natural ion beam generated in the chamber is too small to place a several centimeter-sized objects in the wake and expands radially outward. To correct this, electrostatic lens configurations are designed to expand and refocus the ion beam. Optimization algorithms are used to determine the ideal electrostatic lens configuration, and the design, installation, and characterization of these lenses are presented. The experimental and numerical simulations show good agreement, enabling the installation of simple electrostatic lenses for ion beam manipulation in vacuum systems. Representative cislunar spacecraft wakes are then successfully generated and measured in the ECLIPS vacuum chamber.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"649-660"},"PeriodicalIF":1.3,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulations indicated that the polyvinylidene difluoride (PVDF) binder melted because the temperature exceeded the melting point. The maximum thermal stress acting on the Al foil and the volume expansion of the surrounding medium were 41% and 20% larger in air than in water, respectively, resulting in a greater expansion force and pulverization of the sample in air. The separation mechanism by pulsed discharge is the decrease in adhesion at the interface due to PVDF melting and the thermal stress acting at the timing that prevents Al from tearing. Thus, the separation by pulsed discharge is based on the control of Joule heating and its heat conduction.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"678-687"},"PeriodicalIF":1.3,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10937301","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tracing the evolution of a resonance, therefore, requires a long time for each step. Reproducible events allow us to record data in the time domain at different fixed frequencies and then to rebuild the resonance shapes at different times. Using this method, the ignition process and the transition from electrostatic to electromagnetic coupling (<italic>E–<italic>H) have been investigated for plasma formation in different gases (He, Ar, N2, and O2) and pressures (20–2000 Pa). The microwave source used offers a miniature model of an inductively coupled plasma (ICP) inside a quartz tube and has a relatively narrow resonance in the range of 2.4–2.5 GHz with or without plasma. After a short time with only capacitive coupling, at low pressures, there is a coexistence of two resonances, indicating that capacitive and inductive coupling exist. At high pressures, the ignition time is much longer, and a common hybrid resonance appears. Helium and argon show an increase in time over tens of microseconds of the resonance frequency corresponding to inductive coupling, which means, in our global model, a very slow increase of the electron density. Nitrogen and oxygen show, on the contrary, a relatively long initial phase of capacitive coupling and then a stable electron density with inductive coupling. Moreover, oxygen at high pressures shows a plateau, initially indicating an attachment of electrons to oxygen atoms (O<inline-formula> <tex-math>$^{-}$ </tex-math></inline-formula>) and after hundreds of microseconds followed by the formation of positive oxygen ions.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"571-578"},"PeriodicalIF":1.3,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, Using the Bhatnagar–Gross–Krook (BGK) collision model, this study calculates the transmission coefficient of electromagnetic (EM) waves in the inhomogeneous medium comprising fully ionized dusty plasma and Al layers through the scattering matrix method (SMM). The transport characteristics of left-circularly polarized and right-circularly polarized waves in inhomogeneous fully ionized dusty plasma containing an Al layer are analyzed in the presence of an external magnetic field. The effects of magnetic field intensity, Al layer thickness, and other dusty plasma parameters (dust particle density, dust particle radius, electron density, and effective collision frequency) on the propagation characteristics of EM waves in fully ionized dusty plasma and inhomogeneous media of Al are analyzed in the GHz band. The findings reveal that aluminum significantly impedes EM wave propagation, with increased Al layer thickness exacerbating the obstruction of EM waves penetrating the fully ionized dusty plasma. In addition, magnetic field intensity and different dusty plasma parameters also affect the propagation characteristics of EM waves in the fully ionized dusty plasma containing Al to different degrees. These results provide a theoretical basis for alleviating the blackouts problem of hypersonic spacecraft during flight.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"806-812"},"PeriodicalIF":1.3,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
