The lamination of substrates with thin coatings is commonly used in furniture, automotive and avionic industries. In the lamination process the hot melt adhesives are widely used and typically activated at temperatures from 80°C to 140°C by resistive heating. This requires a heat transfer through the coating and/or the substrate. To make the process more flexible, to decrease its energy ...

The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from a two arm Archimedes spiral coil. The performance of particular interest is knowledge of the radiated magnetic field H and electric field E in the neighborhood of the coil. The results in this paper illustrate how COMSOL is used to solve for the radiated ...

Waterflooding and steam-flooding are used worldwide for EOR. Recently, CO2-flooding has attracted global attention as a means of EOR as well as for carbon capture and sequestration. These processes cause significant changes over time in the fluid composition of oil reservoirs. This paper demonstrates the feasibility of a borehole transient electromagnetic (TEM) system that can map the fluid ...

The electron beam emitted backward by Plasma Focus devices is being investigated as a radiation source for IORT (Intra-Operative Radiation Therapy) applications. A Plasma Focus device is being developed to this aim. The electron beam is driven through an electron pipe made of stainless steel to impinge on a 50 ?m brass foil, where conversion X-rays are generated. Electromagnetic forces in the ...

This work presents the results of a 3D numerical magneto-hydrodynamic (MHD) simulation of an electromagnetic DC pump for liquid metal using a rectangular metal flow channel subjected to an externally imposed transversal inhomogeneous magnetic field. In this study. 3D numerical simulation based on the finite element method was carried out using the computer package COMSOL Multiphysics 3.5a. The ...

We describe methods and results of simulations done for predicting behavior of particles in an aqueous solution under an applied AC electric field on electrodes of rectangular and triangular shapes. Here the two major effects which come into play are Dielectrophoresis and AC Electroosmosis. Two simulations have been presented, one for rectangular and one for triangular shaped electrodes. We have ...

In our recent experiments we are revisiting the topografiner technology for the imaging of surface topography with a resolution of a few nanometers. In these new technique called Near-Field Emission Scanning Electron Microscopy (NFESEM), low-energy electrons are emitted from a polycrystalline tungsten tip via electric-field assisted tunneling. In order to characterize and improve the ...

Radio frequency (RF) heating have potential as alternatives to chemical fumigation for disinfesting legumes. This study was conducted to investigate the feasibility of RF selective heating of insect larvae in 3 kg soybeans packed in a rectangular plastic container using a 6 kW, 27.12 MHz RF heating system. A finite element based computer simulation program-COMSOL Multiphysics® was used to solve ...

The brain is a heterogeneous porous medium with regions of anisotropy. Measurements of tortuosity (λ) showed that diffusion in gray matter (e.g. striatum) is isotropic (λ = 1.65), whereas it is anisotropic in white matter (e.g. corpus callosum) (λparallel = 1.38, λperpendicular = 1.80)[1-2]. Pressure-driven convection-enhanced delivery (CED) of macromolecules (e.g. drugs) was first described in ...

An electrostatic headphone includes many interrelated design elements that affect the frequency response of the headphone and the users listening experience. Xi Engineering Consultants (XI) partnered with Warwick Audio Technologies (WAT) to investigate the complex behavior of one-side electrostatic speakers. Xi developed a GUI that helped WAT engineers optimize their speaker using virtual tools ...
