We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good margin against electrical breakdown. By using a three-dimensional electromagnetic model of the entire power ...

Design of Microwave Resonance Cavity (MRC) to generate non-thermal plasma to treat NOx and SOx from marine diesel engine is presented in this paper. Microwave frequency of 2.45GHz is used generate the required plasma. A number of wave guides are used to transfer the microwave energy into to MRC from the microwave source. COMSOL multi-physics software is used to model the waveguides and to ...

As it is known nano-sized emitters (such as atoms, quantum dots and point defects in diamonds) interaction with nano-environment leads to drastic changes of their decay rate and therefore lifetime (Purcell effect). To calculate the influence in general one needs to solve equations of quantum electrodynamics. However in weak interaction limit these emitters can be considered as point electric ...

I introduce a model of fluidized reactor which, in presence of heterogeneous platinum-based catalyst, decomposes liquid formic acid producing gaseous mixture of carbon dioxide and hydrogen as the product. I treat the physical system as a (Class II) mixture of four constituents - namely formic acid (FA), Platinum micro-pellets (Pt), carbon dioxide (CO_2) and hydrogen (H_2) - which can be, without ...

In this work, a bimetallic strip based thermal sensor was designed using MEMS module of COMSOL Multiphysics® software to monitor the temperature rise in insulating oil which was used as coolant in transformers. The bimetallic strip was designed with different shapes such as cylindrical, rectangle, square & conical and different compositions such as Al/Steel Alloy and Fe/Cu which can withstand ...

Dielectrophoresis (DEP) is an electric field driven technique that has important applications in the enrichment, concentration and isolation of biological and non-biological particles. The assessment of particle trapping capacity using DEP, however, has been qualitative in nature; since current mathematical models are in an early stage and more sophisticated models are under development . ...

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 ...

In the past decades, equilateral polygonal microcavity lasers with whispering-gallery modes (WGMs) have attracted great attentions due to their potential application in photonic-integrated circuits. Compared to the perfect microdisk without deformation, the polygonal microcavities such as triangle, square, hexagonal and octagonal can easily realize the light directional emission and single mode ...
