Charged particle accelerators require large dipole fields with stringent homogeneity requirements needed to bend particle beams without defocussing. Commonly superconducting saddle coil magnets are used with an iron core to enhance the bore field. The iron uneven magnetization brings ... En savoir plus
In this work, we present the effective properties of nanodielectrics with gold (Au) nanoparticles embedded in polymer (Polyvinyl Pyrrolidone (PVP)) matrix, calculated by using finite element method (FEM) based simulation in COMSOL Multiphysics software. Drude model is used to calculate ... En savoir plus
This paper presents the quasi-TEM two-dimensional (2D) approach for the analysis of multiconductor transmission lines interconnect in single and two-layered dielectric region using the finite element method (FEM). FEM is especially suitable and effective for the computation of ... En savoir plus
Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous ... En savoir plus
Parametric finite element simulations were performed to study the effect of film thickness, and electrode size on the different impedance parameters for insulating thin films deposited on a conductive substrate. COMSOL Multiphysics® was used to solve the quasi-static form of Maxwell’s ... En savoir plus
A beneficial method for transporting highly viscous hydrocarbons (e.g. heavy oil and bitumen) through a pipeline is known as Lubricated Pipe Flow (LPF). A major challenge for this technology is flow instability caused by the formation of a wall-coating of oil or the thinning and/or loss ... En savoir plus
Superparamagnetic micro beads offer some attractive applications in biological and biomedical fields. Some of the important applications include manipulation and separation of cells, isolation of specific cells, active drug delivery, magnetic cell separation, separation of proteins, and ...

High-resolution imaging is useful in oil and gas exploration to identify producing fractures that can be in the millimeter thickness range. In principle, high-resolution imaging maybe achieved using “current injection” to measure the electrical conductivity of the formation. Two current ... En savoir plus
Transient eddy current (TEC) technique is being developed for detection of flaws located at depth within multilayer aluminum structures. The present work involves finite element modeling using COMSOL Multiphysics software to simulate different types of probes by changing some of these ... En savoir plus
This paper presents the fast computational and modeling of multiconductor transmission lines interconnect in non-homogenous multilayered dielectric media using the finite element method (FEM).
