Application of Multiphysics in the Simulation of Metallurgical Processes
In the steelmaking processes, the stirring of the metal bath by argon (or nitrogen) injection is a widely used method to achieve chemical or thermal homogeneity. Computational fluid dynamics can be used as a very powerful tool to gain an insight into the mass transfer and heat transfer ... Per saperne di più
2D Axial-Symmetric Model For Fluid Flow And Heat Transfer In The Melting And Resolidification Of A Vertical Cylinder
Laser direct deposition is a process, different from molding or machining, which allows the producing of fully densified and operational components. This technique involves injecting metal powder through a coaxial nozzle into a melt pool obtained by a moving laser beam. The final object ... Per saperne di più
Microfluidic Design of Neuron-MOSFET based on ISFET
In this paper we suggest a device which combines the operation of a neuron-MOS and an ISFET. An ISFET is an ion-sensitive field effect transistor used to measure ion concentrations in a solution; when the ion concentration changes, the current through the transistor changes accordingly. ...

Solving Two-scale Transport Laws During Frying of Foods Using COMSOL Multiphysics
Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based ... Per saperne di più
3D Thermal-Diffusion Analysis on a Moisture Loaded Epoxy Sample
COMSOL Multiphysics was used to simulate an experiment in which the hygroscopic swelling in an epoxy material was measured along a temperature ramp. A simultaneous solution was sought for temperature and moisture concentration distribution in a moisture loaded epoxy sample. Initially the ... Per saperne di più
Modeling of Ferrofluid Passive Cooling System
A ferrofluid contains nanoscale ferromagnetic particles suspended in a carrier liquid. It is used in some high-power acoustic speakers to cool the drive coil. The ferromagnetic particles far from the heat source are attracted by the drive coil’s magnetic field. As the fluid approaches ... Per saperne di più
FEA Simulation of Passive Ferrofluid Cooling Systems
Here we investigate a promising passive cooling method through making advantage of the unique properties of ferrofluid. When a magnetic dipole or a permanent magnet is put at the hot side of a system, it will attract the cold ferrofluid to the hot place and displace the hot ferrofluid ... Per saperne di più
