Introduction: Development of next-generation chemical processes that have zero emissions is a key environmental objective for sustainable development. The manufacture of H2SO4 by the air oxidation of SO2 to SO3 is an important technology where an opportunity exists for new catalyst development and process innovation by reducing emissions of unconverted SO2 in process reactor tail gases owing to ...

Mathematical Modeling has a long history in developmental biology. Advances in experimental techniques and computational algorithms now permit the development of increasingly more realistic models of organogenesis. In particular, 3D geometries of developing organs have recently become available. In this paper, we show how to use image-based data for simulations of organogenesis in the COMSOL ...

COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the resulting interfacial thermal stresses. Experimental data from the raw materials are implemented in the model ...
Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording
Queen's University Belfast, Belfast, Northern Ireland, UK
A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is therefore required. The RF Module and COMSOL Multiphysics® software are used to investigate the plasmonic ...

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 down, some of them fall slightly from the substrate. Stress in the boundary layer, caused by different ...

In this paper, we investigate the compressional wave generation in droplets and use different techniques to correlate the compressional wave generation to the shape of the droplets. Results show a good correlation between eigenmodes predicted by the theory and those experimentally observed.

The control of the flux within continuous casting systems used in the metallurgical field can be obtained through the application of electromagnetic. The model here has been solved through a linear time-harmonic solver. The results of the electromagnetic model have then been applied to the fluid-mechanics model through volume Lorentz forces.

The heating-up of existing dense plasma with short laser pulses is modelled with COMSOL Multiphysics. The interaction between plasma and the laser beam as a longitudinally pumped light source is discussed. The required properties of the plasma, according to the radial profiles of the temperature and the density, are exemplified.

Accurate modeling of magnetostrictive materials and devices requires coupling of electrical, magnetic, mechanical, and possibly acoustic domains. There are relatively few finite element software packages that include all these physical models and even fewer that include magnetostrictive models. Comsol Multiphysics was used to create linear magnetostrictive models with fully coupled physics. ...

The purpose of this study was to develop mathematical models of the coupled electro-thermal process in selected, typical contactors that could then be validated and verified by comparing model predictions with the results of previous studies and with experimental data obtained during a temperature rise test. The study employed Finite Element Analysis using COMSOL to simulate coupled ...
