Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. This work presents a robust approach to the design of EM Shielding based on Graphene (Gph) layers. It is a two ...

Fluid flow has the potential to provide significant mechanical energy input for electromagnetic energy harvesters. The effect of a bluff body, such as cylinder played a significant role in the creation of a Karman vortex profile in the fluid flow. We study the effect of the number and position of the Duffy cylinder on the characteristic of the aerodynamic system of the elastic belt such as the ...

The numerical results of the unconfined compression test on a sample of Articular Cartilage (AC) are discussed. AC is modelled as a load-bearing, deformable, fiber-reinforced material filled with an interstitial fluid and comprising statistically oriented collagen fibers, chondrocytes, and a matrix of proteoglycans. A strain energy is assigned to characterize the mechanical behavior of the ...

Photo-bioreactors generate biomass by providing a controlled environment for the cultivation of algae due to photosynthesis. Algae cultivation can be controlled through the operating parameters and bioreactor environment to allow for high productivity and the use of systems with large surface-to-volume ratios offers maximum efficiency in the use of light compared to alternative batch systems. ...

引言 钒液流电池储能技术作为高效电化学储能技术之一，可应用于新能源储能，电网削峰填谷、调频调幅、应急电源等。钒液流电池储能技术具有独立的的额定功率和额定能量，高输出功率，低成本等特点。 COMSOL Multiphysics® 的使用 本文采用分区建模，模型耦合的方式进行模拟。 结果 钒液流电池在组装过程中需要一定的组装压力以避免电解液的泄漏，同时可减小电极与集流板的接触电阻。如图1所示，有研究表明有流道的集流板与石墨毡电极接触并挤压时，由于流道脊与流道的不均匀表面，会使石墨毡电极出现非均匀压缩现象。图2为均匀模型(SU-5)与非均匀模型(SNI-5)电池压降与实验结果(Exp-5)在CR=55.67%的对比。结果显示考虑了石墨非均匀压缩导致的变形之后的模拟结果与实验结果相吻合。图3为非均匀模型与均匀模型在CR=41.83%情况下的对比图。如图所示 ...

Adequate cooling of beverages is a major issue in planning of several types of events, e.g. poster sessions at conferences. One crucial factor is the time needed to cool beverages from its initial temperature to the desired drinking temperature. We present a way to determine a close approximation for the cooling behavior of three types of commonly used beverage containers using COMSOL ...

Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface with the nervous system. Note that electroceuticals follows medical devices’, rather than pharmaceuticals’, ...

Renewable energies generate temporary mismatches between energy demand and supply. The conversion of surplus energy to hydrogen and its storage in geological formations is one option to balance this energy gap. Storage in deep saline aquifers is the most cost-effective option for underground hydrogen storage (Lord et al., 2014). A 3D multiphase flow model in a dome shaped geological formation ...

Various hydrocarbon compounds have been converted into pure hydrogen by using a catalyst and a palladium membrane in one reactor (PMR) in a one-step process where the reaction proceeds to almost complete conversion. Octane is converted into pure hydrogen using of a palladium membrane reactor is described. Catalysts are used to endorse reactions such as methane steam reforming. These reactions ...

Impedance spectroscopy is a measurement technique that has been investigated in a wide variety of medical applications. An example is the measurement of the dielectric properties of the skin and underlying tissue using sensors placed in contact with human skin with capacitive fringing field electrodes. The aim of this work is to use finite element methods for optimizing the sensor design ...
