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, smaller plant size and lower cost of production. Models for such reactors need to be able to describe both the ...

This paper presents the use of the multiphysics package COMSOL for teaching heat and moisture transport modeling in the research area of building physics. It includes a description on how COMSOL works and six exercises with 2D, 3D, steady state and transient models. It is concluded that COMSOL is a very useful tool for this kind of engineering education. Especially, the abstraction level of ...

COMSOL Multiphysics® 4.0 was used to study conductive and convective heat transfer from the human eyeball to the surrounding air. Postmortem temperature decay curves were collected in eyeballs of numerous human corpses. Of course, these curves represent only a portion of the complete temperature decay curve, since the pathologist is able to start collecting temperature data only after some ...

This work talks on simulation of a ventilating structure for an industrial burner. The mathematical model is based on the frozen-rotor technique, and the numerical simulation is used for resolution of fluid dynamics equations for the air flow into the rotating wheel and into the static volute of the fan. The numerical results obtained with COMSOL’s CFD module are compared with experimental data ...

In this work we want to explore some techniques, microfluidic and electrospray-ionization based, suitable for dynamic microarrays\' fabrication. The fabrication techniques are based on manipulation and self-assembly of selective coated micro and nanobeads. The simulation will include electro-osmotic flow, species transport, and electrostatics.

In this paper, a methodology to simulate the electric behavior of spiral inductances is presented and discussed. All the methodology is built with the COMSOL software used with the Matlab scripting interface and then allows performing fully parameterized simulations. The program architecture is explained and is used to simulate two applications. The first calculates the voltage induced by an ...

Carbon Nanotubes (CNTs) have remarkable mechanical, thermal and electrical properties. The properties of CNTs depend on atomic arrangement (how the sheets of graphite are rolled), the diameter and length of the tubes and morphology of nanostructure. In this paper effective elastic properties of CNT based polymer composites are evaluated using a square Representative Volume Element (RVE) in ...

Electric fields are present in biological systems at multiple spatial and temporal scales. Electroosmotic flow results from the action of electric field on the electrical double layer, formed at the fluid/solid or fluid/membrane interface and characterized by its zeta-potential. For the physiological value of zeta-potential (50 mV) and a single charged protein of average size, electroosmotic ...

In this paper an EMVD (Electro-Mechanical Valve Drive) for combustion engines is redesigned to achieve a fail-safe behavior when power loss occurs. The AC/DC Module and the Moving Mesh interface of COMSOL Multiphysics 4.2 are used to build up a transient model. This model also includes the calculation of eddy currents.

A three phase transformer with very low harmonic pollution transferred back to power line is here presented. In fact, thanks to the described setup, intermediate harmonics (5th and 7th) are not going out back to the power line feeding the primary. These results has been extensively validated versus measurements performed on produced and shipped machine. With these results, TMC is then featuring ...
