Kinetics of the Carbothermal Reduction of Ilmenite: Grain Pellet Model
A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 ... Read More
Magneto-structural Analysis of Fusion grade Superconducting Toroidal Field Coils
In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... Read More
Thermal analysis of a spent fuel transportation cask
Spent fuel transportation casks are required to meet among others (test conditions), the regulatory thermal test conditions in order to demonstrate their ability to withstand specified accidental fire conditions during transport. This paper describes the transient thermal analysis ... Read More
Analyzing the Influence of Electric Field on Flame Through Electro-Hydrodynamics
The effects of electric fields on combustion flames have been studied by using several types of experimental techniques as well as few numerical methods. The flame is influenced by the electric field mainly due to the charges present as a result of chemical reactions that take place in ... Read More
Chip Drop After Silver Sintering Process
Since a couple of years, sintering becomes more and more important for power electronics. To press a semiconductor under high temperature in silver paste on a substrate promises benefits for durability. Tests with semiconductors of different thickness expose some problems. After the cool ... Read More
Multi-Scale Modelling of Catalytic Microreactors
Microreactors are important alternative to conventional reactors in chemistry, chemical, pharmaceutical and semiconductor industries due to their operation characteristics such as increased mass and heat transfer, uniform flow, safety, high throughput through array configurations, ... Read More
Study of Artificial Molecular Engines Action Through COMSOL Multiphysics® Program
Rotaxanes are a class of molecules recently developed in laboratory that have been heralded as possible molecular motors. The motor is constituted by a linear molecule (thread) and a ring-shaped molecule (macrocycle), which is free to move along the thread, switching between two, or ... Read More
A Consistent Environment for the Numerical Prediction of the Properties of Composite Materials
The current paper focuses on the creation of a consistent environment for the numerical prediction of the physical properties of polymer composite. A limitation factor for the successful simulation of composite processes is the correct estimation of the effective properties depending on ... Read More
Plasma Edge Simulations by Finite Elements using COMSOL
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 ... Read More
Modeling of Microstructures in Dissimilar Copper/Stainless Steel Electron Beam Welds
In the case of electron beam welding of copper with stainless steel, two principal cases of welding pool morphology are possible: a droplet-like microstructure where the electron beam deviates to the copper side due to the thermoelectric effect, so the volume of molten copper is much ... Read More
