Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such method that makes use of electromagnetic induction to detect and characterize surface and sub-surface flaws ...

The physics of rotating cups and disks is an important research subject in many areas of engineering. The rotating cup/disk has been employed in many industrial applications such as spin-coating of phosphor on television screens or photoresist films on silicon wafer, concentrating solutions by evaporation, centrifugal atomization of metal melts, and glass flakes production. In this work the ...

Electrostatically excited plasma waves can induce a “plasma wind” in the surrounding media or air. The lifted object has a shape of a flying saucer, just for better illustration. A travelling plasma wave propulsion requires a pre-ionized media around the surface and a travelling electrostatic field. A simplified plasma model was used to set up an EFD (electro fluid dynamic) approach into a ...

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage electrode serving as source of heat. Physics involved are Electrostatics and Laminar Flow with Heat Transfer. ...

Since 2011, LATMOS has been involved in the development of Micro-ARES, an electric field sensor forming part of the DREAMS science payload of the ExoMars 2016 Schiaparelli entry, descent and landing demonstrator module (EDM). Micro-ARES is dedicated to the very first measurement and characterization of Martian atmospheric electricity. The instrument, a compact version of the ARES instrument ...

Airliners are often subjected to dangerous atmospheric and weather hazards among which lightning strikes represent a threat for flight safety. Recently, the use of Carbon Fibers Reinforced Composites as structural parts in aircrafts as an alternative to traditional metallic materials. Unfortunately, most composites are not able to dissipate lightning currents as the traditional metals. Such ...

Several commercial CFD companies have recently extended their codes to magnetohydrodynamic (MHD) flows. However, there are many computational challenges associated with MHD flows under the harsh fusion environmental conditions that require such codes to be carefully examined in a special range of flow parameters and geometries. Among the commercially available CFD tools, COMSOL Multiphysics, a ...

A teaching platform that could be used to help students understand concepts such as; flux linking and mutual inductance has been developed using the AC/DC Module of COMSOL Multiphysics®. This is achieved through the accurate determination of different magnetic flux density components within the proposed geometry. Furthermore, based on the structure configuration, students can use obtained ...

Electromigration induced failure is one of the main reliability issues for the microelectronics industry. The continuous scaling of the interconnect dimensions leads to higher operating current densities and temperatures, which accentuates the electromigration failure. As a consequence, electromigration still poses challenges for the development of the new technological nodes. Electromigration ...
