The use of plasmonic effects to dramatically enhance the electromagnetic field near the surface of a metallic nanostructured surface has grown into a large research area in the effort to take advantage of the surface enhanced field. In this paper the electromagnetic field near a nano ... En savoir plus
The present paper describes the results of a Finite Element Model used to analyze sound propagation in lined ducts. By means of a numerical model it was possible to predict the insertion loss inside rectangular lined ducts in a frequency range from 250 Hz to 4000 Hz. The model was ... En savoir plus
The sensor type developed by Gunytronic uses corona discharge for measuring flow rates in exhaust streams of automotives, aircrafts and industrial plants. This paper will present the development of testing equipment used in laboratory for investigating physical relations on corona ... En savoir plus
Three-dimensional finite element (FE) modeling of magnetic flux leakage (MFL) technique has been performed using COMSOL 3.4 for prediction of leakage fields from surface and sub-surface defects in a 12 mm thick carbon steel plate. The tangential and normal components of leakage fields ... En savoir plus
A biconcave-shaped Red Blood Cell was trapped and deformed in a dual-trap optical tweezers. The two highly focused trapping beams of Gaussian intensity distribution were modeled as background field in the COMSOL Radio Frequency Module. The 3D radiation stress distribution on the cell ...

The tertiary current distributions on rotating electrodes are studied in this work. An acid copper sulfate electrolyte is used within an electrochemical cell of practical dimensions. The distributions of ion concentrations are obtained by the two-dimensional fluid flow simulation and the ... En savoir plus
The Polymer Electrolyte Membrane fuel cell is one of the most promising green technologies for addressing portable, as well as transportation power needs. However, the science behind the fuel cell, in many regards, is still an enigma, and even more so, with the vast numbers of novel ... En savoir plus
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 ... En savoir plus
In this study, COMSOL®4.2a is used to model a microwave heating process in a TE10 rectangular waveguide. The sample consists of a small cylindrical Ca-alginate gel (D = 8 mm, H = 10 mm) inoculated with bacteria Escherichia Coli K12. The sample is placed along the microwave propagation ... En savoir plus
The job of designing end-winding corona protection (ECP) system is one of the very important and complex phases for insulation configuration of high voltage rotating machines. This complexity stems on one hand from the highly nonlinear characteristics of the ECP material and on the other ... En savoir plus
