Image-Based Feature Extraction Technique for Inclined Crack Quantification Using Pulsed Eddy Current

Chinese Journal of Mechanical Engineering, 2019
Existing eddy current non-destructive testing (NDT) techniques generally do not consider the inclination angle of inclined cracks, which potentially harms a larger region of a tested structure.

Analytical time-domain model of transient eddy current field in pulsed eddy current testing

Acta Physica Sinica, 2010
The transient eddy current field is analytically modeled by applying inverse Laplace transform to pulsed eddy current testing. The closed-form solution to transient eddy current field in a complex domain is obtained by using the truncated region eigenfunction expansion (TREE) method and the theory of reflection and transmission of electromagnetic waves.

Multigrid-reduction-in-time for Eddy Current problems

, 2019
Parallel-in-time methods have shown success for reducing the simulation time of many time-dependent problems. Here, we consider applying the multigrid-reduction-in-time (MGRIT) algorithm to a voltage-driven eddy current model problem.Comment ...

High field x-ray diffraction study on a magnetic-field-induced valence transition in YbInCu4

, 2005
We report the first high-field x-ray diffraction experiment using synchrotron x-rays and pulsed magnetic fields exceeding 30 T. Lattice deformation due to a magnetic-field-induced valence transition in YbInCu4 is studied. It has been found that the Bragg

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Eddy Current Pulsed Thermography with Different Excitation Configurations for Metallic Material and Defect Characterization

Sensors, 2016
This paper reviews recent developments of eddy current pulsed thermography (ECPT) for material characterization and nondestructive evaluation (NDE). Due to the fact that line-coil-based ECPT, with the limitation of non-uniform heating and a restricted ...

Extreme magnetic field-boosted superconductivity

, 2019
Applied magnetic fields underlie exotic quantum states, such as the fractional quantum Hall effect and Bose-Einstein condensation of spin excitations. Superconductivity, on the other hand, is inherently antagonistic towards magnetic fields.
