A Computational Fluid Dynamics study has been performed for a Gas Electron Multiplier (GEM) detector of high energy charged particles, currently under development as part of a new tracker of the high luminosity spectrometers in Hall A at Jefferson Lab. By gradual modifications of the geometry simulated in COMSOL, the design of the frame separating two GEM foils has been optimized with the aim ...

This paper showed that: * SAG-MOCVD is a powerful tool to fabricate OEICs and is also effective to extract true surface kinetics during MOCVD. * GaAs-MOCVD process was examined by SAG analysis where it was seen that below 600ºC, surface kinetics shows non-linear behavior. * Surface reaction rate constant of adsorbed species was constant against offset angle, while adsorption equilibrium ...

Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming slower as the water level in the pit lake rises. The rise of the surface of the lake decelerates due to the bigger ...
Investigation of Transport Phenomena in Nanochannels and its Applications in Energy Conversion using COMSOL Multiphysics
Green Energy and Environment Research Laboratories, Industrial Technology Research Institute, Chutung, Hsinchu, Taiwan
Well‐designed and controlled nanochannels are ideal physical modeling systems to study fluidics in a precise manner. Electrokinetics refers to transport phenomena related to the non‐electroneutral EDL, which is created to neutralize the surface charges produced on surface. Surface charges are produced by the dissociation of surface functional groups. We created a mathematical model of a ...
Modeling Charge/Discharge Heat Generation of Li-ion Cells and Experimental Verification of Temperature Distribution
 Kobelco Research Institute, Inc., Kobe, Hyogo, Japan
Modeling the heat generation and the heat transfer of the electrode of lithium-ion battery are introduced. There are several models, such as an homogeneous heating model and a model considering the current and reaction distribution of electrode. Generally, electrodes have large area and the calculation load of the model becomes high. Therefore, some approximated models are required to analyze ...

Even though sonochemical reactors have been studied extensively for decades, there is limited data on their characterization when the volume of the sample is fixed. The Acoustics Module and COMSOL Multiphysics® software are used to resolve the pressure field. The validated numerical model will be used to compare different configurations; changing the Height (H), diameter (D) of the reactor and ...

The numerical study of temperature and acceleration sensitivities of a dual cavity Fabry-Perot (FP) interferometer is carried out using finite element method. The optical cavities are formed by machining two side-by-side circular bore of 12 mm each on a monolithic block of low expansion material. One cavity will be used to generate broadband channel spectra for accurate wavelength calibration of ...
Computational Multiphysics to Optimize Humidification Chamber for a Novel PEM Fuel Cell Power System Used in Automobile Application - new
Tata Motors, Bengaluru, Karnataka, India
Proton Exchange Membrane (PEM) fuel cells are quickly becoming an attractive technology due to their ability to meet increasing energy demands in a cleaner, more efficient way compared to existing methods. A fuel cell is an electrochemical device which converts the chemical energy of a fuel and an oxidant directly into electricity without the intermediate step of classical, chemical combustion ...

Ubiquitous, unobtrusive wearable computing has tremendous potential for impacting many applications including medical, personal entertainment and surveillance. Advances in the underlying technology have allowed for consistent reduction in the size and weight of emerging solutions, with increasing subsystem integration. A key component for the realisation of these systems is the short and long ...

A obtenção de polpa celulósica antecede a produção de papel e envolve a separação das fibras da madeira mediante a utilização de energia mecânica, térmica, química ou a combinação desses processos. Esta operação é realizada em um reator, tubular, cilíndrico e vertical (tipicamente 6 m de diâmetro e 50 m de altura), denominado genericamente de digestor. A madeira é alimentada pelo topo na forma ...
