The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. The optical fiber corrosion sensor based on a side-polished polarizer is realized recently. The polarizer is fabricated by sputtering a Fe film on a side-polished single mode fiber. The new ... Per saperne di più
随着社会进步和发展，能源紧缺的问题日益突出。生物柴油因十六烷值高、无毒、可再生等突出优势正成为新能源开发热点。微波辅助生物柴油制备反应时间短、能耗小、环境污染少，所以设计高效的微波反应釜制备生物柴油势在必行。 针对微波反应器在生产生物柴油时加热不均匀的问题，本文设计了一种可以明显改善微波加热均匀性的夹层釜式微波反应器。然后，再引入能改善物料流体传热的搅拌桨装置。通过电磁场、温度场和流场控制强化液体物料传质传热，进而促进生物柴油的制备。本文所有的仿真工作均通过COMSOL软件进行，分别是用于计算反应器内电磁场分布的“电磁波，频域（emw）”接口 ... Per saperne di più
This work is concerned with the study of the asymmetrical phenomenon observed in three-phase transformers during the standard short-circuit test. The purpose of our work is to see if the asymmetric measurements can be predicted with the use of 2D finite-element models. To this end, we ... Per saperne di più
A simple proximity sensing circuit is made using magnets actuating reed switches; these switches are wired into a larger circuit that performs auxiliary functions. The success or failure of such systems is a function of their position. A simulation using COMSOL Multiphysics is conducted ... Per saperne di più
With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded which results in the thermal limit of the stator winding becoming more of a key constraint. The achievable current density in stator windings is ... Per saperne di più
