Coupled Numerical Modeling and Thermodynamic Approach for SiC Growth Process
Silicon carbide (SiC) single crystals are industrially produced by the physical vapor transport technique. Apart from the geometry of the growth setup, there are two main process parameters that can be controlled: temperature and pressure. To support the development of the process, ... Per saperne di più
3D Modeling of Hydrogen Absorption in Metal Hydride Hydrogen Storage Bottles
The storage of hydrogen as an absorbed element in metal hydride bottles is a promising technique for energy storage. In this work, a three-dimensional model of a charging process in a metal hydride container has been developed to simulate the absorption reaction and resultant heat and ... Per saperne di più
Quantification of Porosity Changes Due to Precipitation of Cement Materials with iCP
The Japan Atomic Energy Agency (JAEA) is carrying out an URL (Underground Research Laboratory) project in Mizunami city, central Japan. The project is a purpose-built generic URL project that is planned for a scientific study of the deep geological environment in fractured crystalline ... Per saperne di più
Using COMSOL Multiphysics to Model Crust Development at the Surface of Whole Beef Meat Subjected to Hot Air Jet
Crust which develops at the surface of meat leads to reactions which affect food color, flavor and safety. Whole pieces of meat are only contaminated by microorganisms at their surface. Thus intense thermal treatment can inactivate pathogenic bacteria; however the associated high ... Per saperne di più
Models for Simulation Based Selection of 3D Multilayered Graphene Biosensors
At the forefront of a new generation of sensors graphene and graphene composite materials are intensively studied for medical and biosensing applications. The outstanding electrical, mechanical and quantum properties of graphene make them a promising material solution to overlap the ... Per saperne di più
Modeling Transient Adsorption/Desorption Behavior in a Gas Phase Photocatalytic Fiber Reactor
Integration or retrofitting of photocatalytic air purifying units into HVAC (Heating, Ventilation and Air Conditioning) equipment is an interesting approach for abating indoor air pollution and removal of volatile organic compounds. An attractive possibility is the use of glass fiber ... Per saperne di più
Modeling of Non-isothermal Reacting Flow in Fluidized Bed Reactors
We investigate a prototype concept of a back-up electricity device where we use liquid formic acid (FA) to produce a mixture of carbon dioxide (CO2) and hydrogen (H2) which is used in a PEM fuel cell, Fig. 1. In the fluidized bed reactor the liquid FA is decomposed to a gaseous mixture ... Per saperne di più
Virtual Functional Product Development of a µ-Methane Steam Reformer
A micro steam methane reformer is a complex product consisting of multiple units. For the virtual functional product development it is necessary to validate these sub models separately. Therefore a reactor was designed to analyse kinetics of chemical reactions. The reactor design is ... Per saperne di più
An Equivalent Kd-based Radionuclide Transport Model Implemented in COMSOL Multiphysics® Software
Radionuclide sorption is often simulated using a lumped approach where retention processes are represented by the distribution coefficient (Kd), which relates the radionuclide mass retained in the solid phase to its aqueous concentration. Classical Kd-based simulations rely on two strong ... Per saperne di più
Ultrasound-assisted Microfluidic Devices: Insights and Optimization of Sono-microreactors
Possible drawbacks of microreactors are inefficient reactant mixing due to the predominance of laminar flow and clogging (when solid-forming reactions are performed or solid catalyst suspensions are used). Ultrasound has been successfully implemented not only to prevent these problems ... Per saperne di più
