本文介绍利用COMSOL传热模块对激光闪射法（Laser Flash Method）测量具有环形结构的碳化硅复合包壳的瞬态传热过程，进而获得对标准激光闪射法估算热扩散率/热导率的几何修正系数和温度修正系数。 碳化硅复合包壳由多层的单质SiC陶瓷基体、SiC纤维编织层组成。碳化硅复合包壳在高温蒸汽中抗氧化性远远优于锆合金，因此被视为未来核电站燃料棒包壳的理想解决方案。为了开展碳化硅复合包壳的性能分析，需要使用激光闪射法获得其在500K~1800K温度范围的热扩散率。问题在于，激光闪射法标准(ASTM E1461-13)规定的样品形状为薄圆片 ... 詳細を見る
Verifying that a local software installation performs as the developer intends is a potentially time consuming but necessary step for nuclear safety related codes. Automating this process not only saves time, but can increase reliability and scope of verification compared to ‘hand’ ... 詳細を見る
Steam drum in a nuclear power plant is one of the important components of Primary Heat Transport (PHT) system where steam is separated from the steam water mixture. Steam water mixture emanating from the reactor core is separated in a steam drum. Separated steam goes to the turbine ... 詳細を見る
This paper presents the investigation into the phenomena during batch reactor vessel mixing comparing agitation equipment; the Rushton turbine and the Marine propeller; in the production of bioethanol by yeast fermentation. The key factors addressed in selecting equipment were fluid ... 詳細を見る
The goal of a tokamak is to use high magnetic fields to contain plasma and produce nuclear fusion that can be used for power generation. MIT’s Plasma Science Fusion Center (PSFC) and collaborators are proposing a machine, the Advanced Divertor eXperiment (ADX) to test new technology for ... 詳細を見る
A pulsed Eddy Current (EC) probe, using the transient response to a stepped voltage is being developed for in-reactor inspection of CANDU® fuel channels. Pulsed EC has the advantage of generating a spectrum of discrete frequencies, allowing the simultaneous collection of data from a ... 詳細を見る
铁芯电抗器具有损耗小、噪音低、维护简单、电抗值线性度好、设计寿命长等优点,得到了越来越广泛的应用。但由于电抗器通风散热不良，导致运行中不同程度的局部过热，造成匝间短路、烧损，甚至引起火灾，严重影响电抗器的安全运行。该问题涉及电-磁-热-流体多物理场耦合，电抗器正常运行时电阻损耗和涡流损耗构成主要热源。本文采用COMSOL Multiphysics®多物理场仿真软件，通过AC/DC模块、传热模块、流体模块对铁芯电抗器的电路、磁场、损耗和温升空间分布进行研究。首先施加激励分别得到铁芯、线圈的磁场及损耗密度分布，然后将铁芯及线圈的损耗值添加为插值，作为流场 ... 詳細を見る
Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world ... 詳細を見る
Recently, due to the dynamically increasing complexity of modern systems, a strong necessity appears for more systematic approaches to high quality control and process monitoring. Requirements imposed by process control in the area of spatio-temporal physical systems also called ... 詳細を見る
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 ... 詳細を見る
