The induction heating coils used in the plutonium casting furnaces at the Los Alamos National Laboratory are studied here. A cylindrical graphite test article has been built, instrumented with thermocouples, and heated in the induction coil that is normally used to preheat the molds ... 詳細を見る

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 ... 詳細を見る

We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module (general ... 詳細を見る

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 ... 詳細を見る

Electrospray propulsion is a contemporary type of thruster technology that electrostatically drives particles through an extractor grid without the need of a pump. The basis of this propulsion system is the coalescence of propellant into a Taylor cone and through a charged extraction ... 詳細を見る

Electrocoalescence is the phenomenon of coalescence of droplets suspended in an insulating liquid or in a gas under the action of an electric field. Electrocoalescence is considered a promising tool in many petrochemical industries for desalting crude oils. However, this technique ... 詳細を見る

High temperature thermodynamic data are crucial for a wide variety of applications in nuclear and aeronautic domains as well as material production processes like glass formation or casting. Contactless acquisition methods are preferred to avoid chemical interactions with the container. ... 詳細を見る

A) Abstract: There has been a spectacular growth in the field of wireless communication in recent years. Current trends in mobile wireless communications demand technologies that allow a single device or system to operate across multiple frequency bands and protocols. This cannot be ... 詳細を見る

This paper describes the implementation of an app for calculating low frequency electric fields outside electrical installations. The app is based on a 2D parametric geometry chosen in such a way that it approximates a large class of electrical installations, which consist of a tower or ... 詳細を見る

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 ... 詳細を見る
