The current general context for green production and decarbonation prompts considering alternative solutions to produce high added value byproducts from gas decomposition without producing CO2. Steam Reforming or Combustion processes, widely applied in Industry, need H2O or O2 to ... Read More

This paper explores the performance of a microfluidic mixer that uses a sinusoidal electric field to accelerate the diffusion process between two Newtonian liquid species in an electrolytic solution. The 2D model was developed using the Microfluidics module in the COMSOL Multiphysics® ... Read More

Electron beam welding process is a high-energy welding technique that uses a focused beam of electrons to join metal components. It is widely used in various industries, including aerospace, nuclear industry, automotive, and electronics, due to its ability to produce high-quality welds ... Read More

Simulation of arc-wire additive manufacturing is under development in many academic and industrial sectors and at different scales. The study at the melt pool scale is often interesting to study deposition shapes and defects but not very relevant to calculate the stresses and strains at ... Read More

This work, which is done in the framework of the SisAl Pilot EU project, presents the use of the COMSOL Multiphysics® software for simulating an ensemble averaged electric arc in a laboratory-scale electric arc furnace. The SisAl Pilot project aims at optimising the silicon production in ... Read More

Experts in the industry are seeing glass substrates as a promising alternative material for interposers, particularly for heterogeneous packaging such as 2.5D or 3D packages [1]. Recently, Intel revealed that they have developed one of the industry's first substrates specifically ... Read More

The velocity field of a fluid flow in an unbounded domain, R, in which the spin of fluid elements is nonzero only within a bounded subdomain, Ri---namely, the interior of a sphere of radius, a---is simulated by equation-based modeling. A change of independent variable motivated by Kelvin ... Read More

Our atmosphere, land, and water are being continuously besieged by pollutants caused by such events as heavy metals leaching from mine tailing ponds, chemical spills from railroad and truck tanker accidents, and petroleum pipeline failures, to name just a few. These environmental insults ... Read More

Working on Faraday’s law of electromagnetic induction, electromagnetic flowmeters measure flowrate on the basis of the electric potential induced when a magnetic flux interacts with flowing water. The electromagnetic coils of the flowmeter are crucial to its operation, given that the ... Read More

When acoustic applications include small geometries, i.e. mm/submillimeter range, so-called thermoviscous effects can greatly affect the pressure response. This paper deals with acoustic topology optimization of such miniature structures with thermoviscous effects taken into account. ... Read More
