Recently, the advanced plasma tools have been using very high frequency power sources (>100 MHz) and their combination to excite plasma utilized in semiconductor technology. This approach is evoking the regimes that are less understood and currently a subject to many studies and ... Read More
Thrombosis is the formation of a thrombus or blood clot within a vessel to maintain the integrity of the circulatory system [1]. The process involves surface interactions, with coagulation leading to the formation of thrombin and a fibrin network, and platelet aggregation [2]. ... Read More
Vacuum window is required in the millimeter wave transmission line in ITER*. It is to be designed to minimize the microwave reflection while keeping a robust and safe approach to meet the requirements. We have studied transmission characteristics of various dielectric materials over D ... Read More
The multiphysics simulation package COMSOL was incorporated into a course in mathematical modeling for chemical engineers. Our implementation for the first year of using COMSOL in the course is described, and assessment results based on examinations and student survey results are ... Read More
高温气冷堆中使用了大量的碳素材料，作为多孔材料，碳素材料含有一定水分等杂质。为了减小反应堆高温运行条件下的堆内材料腐蚀，高温堆在初装堆和事故后需要对一回路进行严格的加热除湿操作。目前一回路加热除湿主要是依靠主氦风机旋转，将动能转换为热能来提升温度。本文将采取另外一种方案，在蒸汽发生器处增加外加热源来加热一回路工质。基于大型商用软件COMSOL Multiphysics建立高温堆内一回路加热的流动传热模型，对两种加热方案的一回路升温过程作数值分析，为高温堆加热除湿方案的选择提供有益的指导。本文中使用的物理场为传热——共轭传热——湍流，多物理场耦合为非等温流动。 Read More
Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... Read More
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’ ... Read More
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 ... Read More
A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 ... Read More
In order to qualify experiments for in-vessel irradiation at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, safety assessments need to be completed and documented to ensure adequate target cooling and structural integrity. Previously, finite element analysis ... Read More
