Plasma gasification of biomass is emerging as an efficient way to reduce the carbon foot print of waste management while generating renewable energy. In general, gasification is a process where electromagnetic wave energy is used to heat biomass sufficiently to convert the bio-mass to ... 詳細を見る
Char combustion is one of the most important reactions in the process of Underground Coal Gasification (UCG). Experiments are performed in a boat reactor under near isothermal condition to demonstrate effects of heat and mass transfer and bed diffusion through ash layer. To obtain a ... 詳細を見る
The High Flux Isotope Reactor, located at the Oak Ridge National Laboratory, is scheduled to undergo a conversion of the fuel used and this proposed change requires an extensive analysis of the flow through the reactor core. The core consists of approximately 500 very thin and long fuel ... 詳細を見る
Existing commercial pyrolysis systems do not have the capability to perform millisecond-scale temporal analysis of pyrolysis vapors that can provide time-resolved experimental data on the reactive and stable gas-phase intermediates predicted by models based on Density Functional Theory ... 詳細を見る
The high temperature measurement of thermal conductivity is vital for predicting nuclear fuel performance both during reactor operation and accident conditions. The proposed method uses experimental thermograms obtained via high temperature laser-flash heating of a disc-shaped sample in ... 詳細を見る
The vacuum arc remelting is a refining process used to melt reactive metals like titanium, zirconium or hafnium. Melting is performed under vacuum to avoid reactions between liquid metal and oxygen which could be a source of pollution. This process is particularly well suited to purify ... 詳細を見る
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]. ... 詳細を見る
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 ... 詳細を見る
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。 詳細を見る
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 ... 詳細を見る
