In the pursuit of effective thermal management for electronic devices, it is crucial to develop insulation interface materials (TIMs) that exhibit exceptional through-plane conductivity, low resistance, and minimal compression modulus. Boron nitride (BN), given its outstanding conduction properties, has garnered significant attention as a potential material this purpose. However, previously reported BN-based composites have consistently demonstrated conductivity below 10 W m
Hall thrusters are widely used as space electric propulsion devices. Due to the complex plasma phenomenon and high computation cost, currently it is difficult fully simulate real physical process in thrusters. Recently, Szabo Taccogna have proposed two different methods simplify accelerate simulation, respectively. In this paper, both these of acceleration analysed compared, then a modified method proposed. order verify acceleration, influence magnetic field gradient on parameter...
According to the experimental dataset on as cast high entropy alloys with cubic structure, relationship between stability and physical parameters of structure has been investigated from view atomic size difference, mixing enthalpy, electronegativity difference valence electron concentration in present work reveal formation alloys. The results indicated that enthalpy is effective parameter can predict solid solutions also play important roles body centred face crystals. Moreover, back...
This paper presents a simulation model on electrostatic levitation of lunar dust particles in the terminator region. Full-particle particle-in-cell simulations are carried out using real ion to electron mass ratio obtain plasma sheath, surface charging, and transition point electric field. Test particle simulate from surface. Results show that condition region is sensitively influenced by ambient altitude varies significantly even for small changes sun elevation angle.
Abstract The generation of a high‐frequency plasmaspheric hiss (HFPH) wave observed by Van Allen Probes is studied in this letter for the first time. has moderate power spectral density (∼10 −6 nT 2 /Hz), with frequency range extended from to 10 kHz. correlated observations waves and particles indicate that HFPH associated enhancement electron flux during substorm on 6 January 2014. Calculations linear growth rate driven fitted phase space show distribution after onset efficient generation....
Full particle particle-in-cell simulations are performed to study the collisionless electron-ion coupling during ion beam emission and neutralization. Simulations show that neutralization propagation two closely coupled processes. Electron-ion is achieved through interactions between trapped electrons a potential well established by of front along direction not plasma instabilities as previous studies suggested. In transverse direction, generates an expansion fan similar mesothermal into...
Abstract We present a multiple‐satellite observation of the magnetic dip event during substorm on 10 October 2013. The illustrates temporal and spatial evolution gives compelling evidence that ring current ions induce by enhanced plasma beta. moves with energetic in comparable drift velocity affects dynamics relativistic electrons radiation belt. In addition, provides favorable condition for electromagnetic ion cyclotron (EMIC) wave generation based linear theory analysis. calculated proton...
Abstract The deep learning method of long short‐term memory (LSTM) is applied to develop a model predict the daily >2‐MeV electron integral flux 1 day ahead at geostationary orbit. inputs include geomagnetic and solar wind parameters such as Kp , Ap Dst speed, magnetopause subsolar distance, value itself over previous five consecutive days. trained on data from periods 1999–2007 2011–2016, efficiency tested 2008–2010 period. We experiment with different input combinations find that when...
Surface coking is significantly affected by the mass transfer of regenerative cooling system in advanced aeroengines. On basis detailed chemical kinetic mechanism China No. 3 jet fuel (also known as RP-3), flowfield and surface RP-3 curved channel surrounding around cavity flameholder scramjet are numerically studied. Results indicate that vortex structure enhances fluid mixing channel, so it improves heat transfers between near-wall region core flowfield. Compared with straight has higher...
The effects of inclination angle θ and unloading rate confining pressure U c on the unloading-induced slip behaviors shale fractures were investigated by conducting triaxial fracture experiments. variations in mechanical stability, frictional behavior, morphology variation systematically explored. results show that with continuous pressure, initiated to slip, then entered quasi-static stage, eventually dynamic stage sequence. occurrence stick-slip events was strongly influenced .
