Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... En savoir plus
氢能燃烧值高且无污染，被认为是人类社会摆脱对化石能源依赖的理想能源。目前氢能应用的主要瓶颈是氢存储。而氢存储的主要方式中，金属氢化物因其安全性高，循环性能好的优点，得到广泛的研究。但由于金属氢化物吸放氢反应的热效应、粉末床的传热和传质特性较差等问题，贮氢罐的吸放氢速率下降，成为限制应用的主要因素。最近十几年，贮氢罐吸放氢过程的数值模拟及相关模型得到广泛的研究。通过数值模拟方法可以优化设计贮氢罐，以期满足实际应用中的需求，同时节约设计成本。本文面对贮氢罐的实际指标(吸氢速率1.5 L min-1)，采用COMSOL软件中的多孔介质传热、地下流动以及数学模块 ... En savoir plus
Microreactors have gained popularity in fuel production industry. This is due to its high surface area to volume ratio, enhanced mass and heat transfer, short residence time and a more sustainable practice. The catalytic hydrodeoxygenation (HDO) reaction of 4-Propylguaiacol (4PG) to 4 ... En savoir plus
Stirred tank bioreactors are used to simulate a natural biochemical environment for the optimum growth of cells (i.e. algae, microorganisms or tissues) in microbial and cell culture. Bioreactor types range from small (5 L and less) up to 15000 L systems for large-scale industrial ... En savoir plus
The IR CO2 laser powered chemical conversions in the gas phase are intriguing and the researchers’ attention was focused on this transformation a while ago. The method, known as Infrared Laser Powered Homogeneous Pyrolysis, or IR LPHP opened reaction pathways not reached by conventional ... En savoir plus
RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For ... En savoir plus
The global demand for sulfuric acid has been forecast to grow at an average of 2.6% per year from 2005 – 2010. The primary objective of this work is to analyze the performance of various heterogeneous catalyst shapes that have been proposed for the oxidation of SO2 to SO3 used in the ... En savoir plus
Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus
Temperature management and homogeneity on wafers has always an important effect on production in all microelectronics fields. The heat resistance of every mechanical contact, not only clamping, may decrease the precision of temperature regulation. But they also increase the difficulties ... En savoir plus
This paper presents a preliminary analysis of the coupled thermo-hydrodynamics and neutronics of circulating nuclear fuel systems in a nuclear reactor that adopts a molten salt mixture. This flows up through channels in a graphite moderated core and plays the role of both heat generator ... En savoir plus
