The blast furnace shaft is a huge counter flow reactor in which heat and mass exchange play a significant role in its mathematical modelling. The heat exchange model is already available in COMSOL Multiphysics® via the Local Thermal Non-Equilibrium interface. This multiphysics coupling ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

The complete modelling of free radical polymerization (FRP) in a flow microreactor is dependent upon various transport processes - mass, momentum and heat transfer alongwith chemical reaction. And top of that, all processes are coupled to each other thus making modelling and simulation ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

The wide bandgap semiconductor silicon carbide (SiC) has drawn increasing attention in recent years as a promising material for high-power, high-frequency, and high-temperature operating devices. These outstanding properties of SiC make it a good candidate to replace silicon in many ... 詳細を見る

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, ... 詳細を見る

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) & ... 詳細を見る
