Electrocoalescence is the phenomenon of coalescence of droplets suspended in an insulating liquid or in a gas under the action of an electric field. Electrocoalescence is considered a promising tool in many petrochemical industries for desalting crude oils. However, this technique suffers from some drawbacks such as short circuiting of electrodes, limitations on applied electric field and its ...

Rotating Magnetic Field Eddy current technique is a promising technique for inspection of flaws in metallic tubular components. Three primary coils, 120 degrees apart in space, are excited with three phase current source, by virtue, a rotating magnetic field polarised in radial direction is generated. This radial field interacts with metallic tube and generates ...

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head avascular necrosis. To enable positive outcome of the treatment, optimal positioning of the electric implant is ...

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 ...

After spinal cord injury (SCI) the functions of the lower urinary tract are often disrupted and may have fatal consequences for the patient. It has been shown that using a transrectal probe developed by Craggs et al., through conditional transrectal stimulation of pudendal nerve, it is possible to treat hyperreflexia in some of the SCI patients. To maximise the efficacy of this type of ...

In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of the electric field. DEP is caused by polarization of the DNA particle. Two different electrode geometries ...

Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as well. Electromagnetic and acoustic or seismic techniques may provide the significant advantage of a mobile non ...
COMSOL Multiphysics Modelling for Measurement Device of Electrical Resistivity in Laboratory Test Cell
C. Rémi, M. Bergeron, and S. Moreau
Bioreactor landfill is based on a homogeneous distribution of the moisture content to increase waste biodegradation. Most of studies have shown that Electrical Resistivity Tomography (ERT) can be a suitable method to study water content variation (2D and 3D). ERT is influenced by many physical parameters and no single relationship with volumetric water content was yet established for Municipal ...

Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor and magnetic material configuration, using finite element analysis (FEA) software to calculate the resulting field, modifying the configuration, and iterating to produce the desired results. We take the opposite approach of specifying the required magnetic field, imposing it as a boundary condition on ...
Electromagnetic Parameters Extraction for Integrated-Circuit Interconnects for Open Three Conductors with Two Levels Systems

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, a new quasi-TEM capacitance and inductance analysis of multiconductor multilayer interconnects is successfully demonstrated using the finite element method (FEM) ...
