In this paper an axisymmetric model of annular linear electromagnetic induction pumps using numerical methods and four approaches (two transient and two quasi-stationary) with different complexity is studied. Comparison of integral characteristics is performed between numerical approaches and also with analytic estimations. Distributions of physical parameters over length and height of channel ...

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 ...

Cochlear Implants (CIs) are implantable prostheses that bypass the non-functional inner ear and directly stimulate the auditory nerve with electric currents, enabling deaf people to experience sound again. The CI electrode array sits inside the cochlea close to the auditory neurons. An ideal stimulation material must have low impedance with maximum charge transfer capacity in the electrochemical ...

COMSOL Multiphysics® software is used to model a water tree in tape shield and concentric neutral cables. It allows for the effect on electric field intensity at the tip of the water tree and electric potential due to the water tree to be better understood. Also, COMSOL is used to calculate the resistance and capacitance of a section of cable with a water tree as it grows across the insulation. ...

High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance (NMR). The HTS NMR system is inserted into the bore of an existing high field magnet. A compensating Helmholtz ...

As the importance of nanoparticles is growing more and more, controlling and understanding the properties of nanoparticles became a focus of research. In this field Meyer at al.  are researching the GMR effect in granular gels to develop magnetoresistive sensors. The GMR in granular gels is simulated to investigate the physical processes in those systems. As soon as the models coincide with ...

Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines . However, due to its low sensitivity the use of NQR is still limited. One way to increase the sensitivity is to improve the RF coil by means of a better RF ...

The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by-product of olive oil production. The modelling includes the PEF effects on the WOP which is flowing through a ...

In this study, COMSOL Multiphysics® software was applied to the investigation of the electromagnetic behavior of an optical crystal submitted to the magnetic field generated by electric current in a near positioned metallic conductor. Moreover, the influence of a ferromagnetic apparatus (magnetic concentrator) on the magnetic field acting upon the crystal was investigated. Three cases were ...

β heat treatment of Uranium rods is carried out for randomization of oriented grains (called texture) developed during hot rolling or hot extrusion operation. During this process, Uranium rods undergo heating of up to 740 Deg C followed by water quenching. The objective of this work is to see the feasibility of direct heating technique for heat treatment application. At present, heat treatment ...
