An analysis to quantify the effects of packed bed channeling in the narrow passages of the ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Each CO2 adsorbent bed is ... Mehr lesen
It is frequently necessary to electrically heat gases; a convenient geometry is the familiar tube-in-shell heat exchanger, where the tube side is modified for electrical heater-rods, and the baffled shell side contains the flowing gas, as indicated in Fig. 1. However, this modification ... Mehr lesen

在新能源汽车中应用GaN表贴器件能够极大提升车载电源的功率密度，提高生产效率，而汽车中高温、高湿、高压的极端应用环境对器件所使用的环氧塑封料提出了更高的防潮耐温要求。本文首先基于菲克扩散定律，采用吸湿试验与COMSOL有限元仿真相结合的办法，对两种常用环氧塑封料的吸湿扩散特征进行了研究，得到相关的湿气扩散特征参数；然后利用COMSOL中的稀物质传递、固体传热、固体力学等模块，对TOLL外形塑封器件在湿热环境中的湿气扩散行为及湿热应力分布进行了模拟；最后基于实际应用，分别对两款环氧塑封料塑封的GaN TOLL器件进行了MSL以及HAST可靠性验证。研究结果表明 ... Mehr lesen
在LNG储罐内常压低温（-162℃）环境条件下，下层液态天然气与上层甲烷等气体（BOG）处于气液两相平衡状态。当储罐泵井底部LNG低温泵需要检维修时，出于安全考虑，需要向泵井内先通入氮气以吹扫置换BOG气体，在后者低于一定浓度后方可打开泵井上方井盖进行吊装作业。本研究建立了LNG储罐泵井中氮气置换BOG的二维动态模型，模拟气液相界面上方气体流动、混合与传质传热现象，并耦合了甲烷/氮气混合气体热力学模型、高温差下浮力效应与LNG在相界面的气化量，对模型关键参数的影响进行数值分析，如氮气流量、气液相界面高度和吹扫气体出口位置等。模拟结果显示，当吹扫氮气温度为20℃，流速为0 ...
