Bloch waves in infinite periodic structures – much in vogue in the present metamaterial age – can be conveniently studied by COMSOL Multiphysics® software. This is demonstrated by a simple, yet rich two-dimensional example: a perforated sheet with square symmetry. Instead of plane waves ... En savoir plus

In this paper, a two dimensional finite element based microstructural model is constructed using Voronoi tessellation for representing polycrystalline material. Elastic wave propagation and Heat diffusion studies are then performed on constructed microstructure model.Computational issues ... En savoir plus

Respect to the previous approaches, in this communication the electrochemical and chemical kinetics as well as the transport phenomena, were modelled at very high level of theory, taking into account all the parameters affecting the galvanic process, including turbulent convection ...

Concrete hydration is a highly exothermic process which, in large concrete structures, produces highly elevated temperatures. While this phenomenon has long been understood to be a negative side effect which can cause thermal stress cracking in concrete structures, a relatively new and ... En savoir plus

Immense amounts of methane are stored as gas-hydrate deposits in deep layers of marine sediments. This has raised considerable interest to develop strategies for producing natural gas from marine hydrates. One potential production strategy is the injection of supercritical CO2 into ...

This paper describes COMSOL Multiphysics® simulations of the stress and crack development in the area where a masonry wall supports a floor. In these simulations one of the main material properties of calcium silicate, its E-value, was assigned randomly to the finite elements of the ... En savoir plus

Resin Transfer Molding (RTM), is a closed mold reinforced polymer composite molding process where the resin is infused under a pressure gradient. The liquid resin is infused through the dry preform and displaces air to saturate the preform. One of the governing parameters in an RTM ... En savoir plus

Enhanced operational flexibility and low levels of pollutant emissions are achieved with a sequential arrangement of premixed combustion stages in gas turbines for power generation. In the second – reheat – combustion stage, hot flue gases of approximately 1500K are enriched with fuel ... En savoir plus

Kiran received his M. S. from Indian Institute of Science, Bangalore and his Ph.D. from University of Sheffield, both in Chemical Engineering. He is currently working as a Senior Researcher at the General Motors R&D, India Science Lab, Bangalore where he is involved in modeling of ... En savoir plus

A simple design for a microfluidic flow system for use in mixing or reacting assays with limited sample availability has been proposed and analyzed using COMSOL\'s multiphysics simulation package. The design is based on differential electroosmotic flow concept which has facilitated a ... En savoir plus
