Although resuscitation during pregnancy is relatively uncommon and rarely causes death, they have a particularly large impact in terms of the mortality of the unborn child and long-term effects on families and society as whole. In this paper, we present a new 3D finite element model of a pregnant female torso which accounts for presence of amniotic liquid and calculate current density ...

Research at Fraunhofer EMI addresses the response of materials in extreme dynamic loads. Besides mechanical or thermal loads, intense electric pulse currents also represent an extreme dynamic load. Experimentally, metallic samples, mainly thick wires, were electro-mechanically loaded with currents up to 400 kA. For this purpose, a test rig containing a high-voltage pulsed power supply and high ...

The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. The strategy is presented, in order to perform a computation that correctly takes the physics into account. In ...

Permanent magnets are ubiquitous in our world today, from refrigerator magnets to industrial sensor applications. Often, the magnitude of the field at a specific distance from an arbitrarily shaped magnet of variable strength is a necessary parameter for end-use systems. We used the the AC/DC module of the COMSOL Multiphysics® software to simulate field strength of permanent magnets for aiding ...

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 hand from the coupled multiphysics phenomena of the involved performance evaluation. Simulation based ECP ...

As interest in the electromagnetic spectrum expands towards the infrared and terahertz range, the distinct advantages of using semiconductors instead of metals for plasmonic applications must be understood. Plasmonic resonances in gold (Au) and indium nitride (InN) gratings are studied, in the terahertz (?=30µm) regime. The electromagnetic properties of Au and InN are described by the Drude ...

Flows of electrically conducting liquids in external magnetic fields are present in several applications. In this kind of flow, the inhomogeneous magnetic field creates a breaking force on the conducting fluid. As a result, a stagnant zone is formed in the zone affected by the localized field so that the fluid flows around it. Wakes in magnetohydrodynamic flows present interesting challenges ...

In ESA's Cosmic Vision program, the Japanese SPICA satellite is a mission of opportunity in the M-class, with the SAFARI instrument being one of the next generation space-borne astronomy instruments being developed to take advantage of SPICA’s cryogenically cooled 3-m class primary mirror. The SAFARI instrument will use large-format arrays of Transition Edge Sensor (TES) bolometers read-out with ...

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 ...
