Present work is done in the framework of the SisAl Pilot EU project, which aims at optimising the silicon production in Europe by recycling materials and using a carbon-emission friendly technology. The silicon production experiments are conducted on laboratory and pilot scales in ... En savoir plus
Introduction Over the last years, there has been an increasing interest in plastic recycling as an alternative to reduce fossil fuel dependency. In this light, chemical recycling has been presented as a promising strategy to maximise the recycling rate, although this technology presents ... En savoir plus
The fabrication of new reactor types has been simplified significantly by the rapid progression within the field of additive manufacturing. A reactor can be fit to nearly every specific task by varying its geometry and therefore its reactant hold-up and flow conditions in continuous ... En savoir plus
叶片复合材料层的击穿是风电机组遭受雷击后的主要故障形式。对于低电导率的GFRP类叶片铺层而言，雷电先导作用下的强背景电场造成的电击穿可能先于回击电弧的热效应产生。为了获得GFRP铺层的电击穿机理，基于COSMOL Multiphysics软件，建立了引下线-GFRP铺层的流注放电数值仿真模型。考虑了空气域与介质层内部的粒子输运，以及气-固分界面上的电荷沉积与注入作用。通过“稀物质传递物理场” 模块、“静电物理场”模块、“边界常微分和微分代数” 模块以及“稳定对流-扩散方程接口” 模块对控制方程进行求解。依据电场梯度分布进行了网格加密与时间步设置 ... En savoir plus
The development of microfluidic components for implementation of a lab-on-chip system requires both fluid movements under a controlled environment as well as sensitive detection. This work involves the design and simulation of micro-reactors with integrated heating as well as optical ... En savoir plus
With the ReactorSTM the relationship between surface structure and catalyst activity under industrially relevant conditions can be investigated. It enables atomic-scale observations of model catalysts under conditions approaching those used by the chemical industry. It consists of a ... En savoir plus
Granular and powdered activated carbons have been widely used for purification/filtration in air and water as catalysts or organic adsorbents. To obtain mechanical filtration capacity and inorganic reduction performance, activated carbon can be formed as a block-shaped porous media, ... En savoir plus
Water disinfection using UV light is a well-known technology. Conventionally, mercury based cylindrical lamps are used, however, recently LED based UV lamps have emerged on a commercial scale. These devices hold several advantages compared to the conventional lamps, e.g. being mercury ... En savoir plus
Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double ... En savoir plus
Prototype Fast Breeder Reactor (PFBR) has two independent, diverse, fast acting & fail safe shut down systems to achieve the required level of safety & reliability (1). The shut down systems comprises of nine numbers of Control & Safety Rod Drive Mechanisms (CSRDM) & ... En savoir plus
