Magneto-structural Analysis of Fusion grade Superconducting Toroidal Field Coils

A. Amardas [1], and S. Dwivedi[2]
[1] Institute for Plasma Research, Gandhinagar, Gujarat, India
[2] COMSOL Multiphysics Pvt. Ltd, Bangalore, Karnataka , India

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. ... En savoir plus

Multi-Scale Modelling of Catalytic Microreactors

B. Hari[1] and C. Theodoropoulos[1]
[1]The University of Manchester, School of Chemical Engineering and Analytical Science, Manchester, UK

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, ...

Mixing and Residence Time Distribution Studies in Microchannels with Floor Herringbone Structures

A. Cantu-Perez, S. Ping Kee, and A. Gavriilidis
University College London, Department of Chemical Engineering, Torrington Place, London, UK

The mixing characteristics and residence time distributions (RTDs) of a staggered herringbone microchannel have been investigated numerically by COMSOL Multiphysics and by particle tracking algorithms that incorporate diffusion via a random walk. All simulations were validated with ... En savoir plus

3D Simulation of an Ethanol Reformer

A. Cifuentes [1], J. Llorca [1], R. Torres [1], S. Rosell [1], J. Grau [1]
[1] Universitat Politècnica de Catalunya, Barcelona, Catalonia, Spain

In order to improve hydrogen production in an ethanol reformer it is needed to understand what happens inside it. Also, a simulated model can simulate different work conditions avoiding the necessity of doing tons of experiments. A 3D computational fluid dynamics simulation study of ... En savoir plus

Exploiting New Features of COMSOL Version 4 on Conjugate Heat Transfer Problems

J.D. Freels[1], I.T. Bodey[2], and R.V. Arimilli[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]University of Tennessee, Knoxville, TN, USA

Recent new releases of COMSOL provide the user with a dramatic new interface from which to interact, and many new features “under the hood” for solving problems more efficiently and with even greater accuracy and consistency than before. This paper will explore several of these new ... En savoir plus

Simulation of the Degradation of Methyl Red by Gliding Arc Plasma

The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... En savoir plus

CFD Investigation of Cross Bubbly Flow through a Bubble Column with Rectangular Geometry

N. M. Musa [1], D. Kuvshinov [1], P. Rubini [1],
[1] The University of Hull, Hull, East Yorkshire, United Kingdom

Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, ... En savoir plus

Numerical Simulation of Pool Film Boiling Heat Transfer during Quenching of Heated Cylindrical Rods
