Eddy currents are based on electromagnetic induction and analysis of electrical currents on conductive materials.This method is used for thickness measurements, corrosion and defects detection, electrical conductivity and magnetic permeability measurements.Recently, it has been exploited as a materials ...
The two applications were tested by Eddy Currents (EC), using both conventional planar spiral probes and a new EC probe developed by some of the authors, called lOnic probe. Four different FSpW conditions were produced and tested in 2 mm-thick plates of duraluminium with and without Alclad...
A 3-D eddy current code, TRIFOU, has been used to simulate eddy currents flowing around cracks in very thick conductors, which is a fully 3-D situation. The measurement set and the probe have also been simulated so that we can compare numerical and experimental output signals. Storage and...
eddy current fields of the plate conductor with two parallel cracks and a cross crack have been studied further.Numerical results computed by the presented integral equation method are compared with those obtained by the finite element-boundary element method(FE-BEM).Good agreement has been found ...
A novel application of the zoom-in technique for 3-D electromagnetic field calculation to 3-D remote field eddy current effect computation is introduced. The technique is especially suitable for problems that are essentially two-dimensional but with some local 3-D character. Significant reduction of...
The aim of this paper is to analyze a numerical method to solve transient eddy current problems with input current intensities as data, formulated in terms... A Bermúdez - 《Ima Journal of Numerical Analysis》 被引量: 7发表: 2012年 Application of the fast multipole method to hybrid finite ...
Eddy Current Testing Figure 1. Eddy current testing is a contact-free technique employed for examining metallic parts. Eddy currents, to put in simpler terms, are fields of alternating magnetic current that are produced when an alternating electric current travels via one or more coils in a pro...
There arise, however, difficulties related to the universal validity of the model. A study of the reasons for these difficulties leads to the alternative approach of large-eddy simulation. Attention is given to the critique of closure modeling, details regarding the large-eddy simulation technique,...
On the role of eddy mixing in the transport of zonal ocean currents The ocean is turbulent at all scales but the nature of turbulence depends critically on the scale under consid-eration and thus turbulence in the ocean com... D Olbers 被引量: 4发表: 2005年 Energetic constraints on the ...
In an induction heating apparatus which comprises a high frequency power source for inducing eddy currents into a plated steel sheet, electronical means are provided in order to vary the frequency of the power source. The variation of th... Katayama Keiichi Hiroshima Techn.Inst. MITSUBISHI,Kato ...
