High temperature processes are used in a large variety of industrial application. Simulation helps to solve technological problems and increase energy efficiency in case of industrial scale simulation. We present in this paper a research equipment simulation. The aim is to increase ... 詳細を見る
Fluid Flow and Heat Transfer Characteristics in a Stirred Cell System for Crude Oil Fouling
A small batch stirred cell which is operated at temperatures up to 400 °C and pressures up to 30 bar is used to study fouling behaviors of selected crude oils. COMSOL Multiphysics package is used for the CFD (Computational Fluid Dynamics) and heat transfer modeling for this stirred ... 詳細を見る
Punch Design for Uniaxial Forging Process of γ-TiAl Using COMSOL Multiphysics®
The increasing demand for improved metallurgical products strongly motivates the optimization of manufacturing processes and design of γ-TiAl products. Among the large variety of available forming processes, cold closed-die forging is particularly suitable for producing net shape ... 詳細を見る
Modeling of High-Temperature Ceramic Membranes for Oxygen Separation
Oxygen transfer through ceramic membranes at high-temperature can substantially reduce costs respect to conventional separation methods. With the aim to improve the determination of the properties of the ceramic materials, a lab-scale permeation set-up was modeled using the Chemical ... 詳細を見る
Large Scale Outdoor Flammable & Toxic Gas Dispersion Modelling in Industrial Environments
HazRes has developed a gas discharge and dispersion model in COMSOL which takes into account the effects of localized wind profiles and turbulence generated by buildings, structures and terrain on the dispersion of gases in question. The main focus of this work is to develop and provide ... 詳細を見る
Fluid Flow Simulation of Preconcentration Membranes Using Finite Elements Tools
We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. ... 詳細を見る
Modeling of Silicon Transport into Germanium Using a Simplified Crystal Growth Technique
A numerical simulation study, using COMSOL Multiphysics®, was carried out to examine the temperature and concentration fields in the dissolution process of silicon into germanium melt. This work utilized a simplified configuration which may be considered to be similar material ... 詳細を見る
Thermo-fluid Dynamics Modelling of Hydrogen Absorption and Desorption in a LaNi4.8Al0.2 Hydride Bed
A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the ... 詳細を見る
Chemical Reactions in a Microfluidic T-Sensor: Numerical Comparison of 2D and 3D Models
In recent years lab-on-microchip technology has become a powerful tool for micro-scale analysis of biochemical processes. In the studied system the overall process consists of transport, convection, diffusion, reaction and adsorption processes. Two compounds A and B, contained in a ... 詳細を見る
