In the nuclear fuel cycle, fluorine is produced by the electrolysis of the molten salt KF-2HF. It is a complex process to study since hydrofluoric acid and fluorine are hazardous and highly corrosive. A 3D-model of a lab-scale fluorine electrolysis cell has been developed to increase our understanding of this process, using the electric currents and the bubbly flow interfaces to simulate the ...

Using a Realistic Human Head model to simulate the effect of electrical stimulation can be useful in understanding field distribution in the brain and therefore, the actual point of stimulation before doing it on human subject. With the help of this model, parameters like the stimulus strength as well as electrode placement and its effect can be tested much more easily while targeting a ...

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of the bricks, in particular the predicted time at which brick shrinkage reverses into expansion, generating large ...

Medium- and high-voltage circuit breakers and reclosers are important grid protection devices that connect different grid sources and increase the network/grid reliability. Currently, there is a clear need of increasing the numbers of switching operation. Therefore, the optimal design of these devices becomes of extreme importance in order to enable the required switching capabilities. This ...

Fusion devices (tokamaks, stellarators) require hundreds of millions degree Celsius temperature to reach the plasma state when the fusion reactions start to occur. Ion cyclotron resonance heating (ICRH) is a method of energy transfer to the ions in the plasma from electromagnetic radiation having a frequency equal to the ion cyclotron motion frequency in the presence of a magnetic field. Studies ...

Airborne particles or aerosols are an unstable system with distributed properties among its individual particulate members. Its fundamental property such as particle size, composition, electrical conductivity, magnetic susceptibility, and morphology could change in response to environmental conditions and could be exploited for collection and other applications. Detection and collection of ...

In a water based electrolytic polishing process, the formation of molecular hydrogen at the cathode is unavoidable and it can contribute to the formation of surface defects at the anode side. This paper presents the work to model and simulate the molecular hydrogen flow inside radio frequency cavity geometries and compares it with the presence, type and relative position of certain defects in ...
复合型电磁轨道发射装置是轨道型电磁发射器研究的一个重要方向，复合型轨道是对轨道的内表面添加保护层，由于电磁轨道在发射时存在复杂的热量变换，轨道表面材料在吸收这些热量之后会发生脱落、气化甚至是电离等现象。为减弱在发射过程中的烧蚀现象，在轨道的表面添加保护层，使轨道内表面材料具有强的耐热性能，并且强度、韧性较好。运用 COMSOL Multiphysics® 软件仿真模拟复合轨道在发射过程中的温度、电流、应力和应变的变化。

Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it is predicted that the nonlocal response blueshifts the resonance peak, modifies the electric field ...
