During the last century, the MagnetoCaloric Effect (MCE) has been widely used for realizing extremely low temperatures. However, it is only in the last three decades that some of the efforts to develop a benign and cutting-edge technology for realizing the ...
Centrifugal pumps are required to sustain a stable operation of the system they support under all operating conditions. Minor modifications of the surfaces defining the pump's water passage can influence the tendency to unstable system operation significan ...
The invention concerns a magnetocaloric device, especially a magnetic refrigerator, a heat pump or a magnetic power conversion machine comprising at least a permanent magnet assembly (4, 11) for generating magnetic flux, a rotating ring (2) coaxially dispo ...
In the frame of the SPS upgrade an accurate impedance model is needed in order to predict the instability threshold and if necessary to start a campaign of impedance reduction. Analytical models, 3-D simulations and bench measurements are used to estimate ...
Cardiovascular diseases have a major impact in Western countries. Mathematical models and numerical simulations can help the understanding of physiological and pathological processes, complementing the information provided to medical doctors by medical ima ...
Nowadays, the general trend towards to minimally invasive interventions is present in all the medical domains. For the surgical intervertebral spinal disc cutting or removal domain, it is particularly a necessity because the manual methods currently employ ...
In a rotary magnetic refrigerator, a porous ring is turning in and out of a magnetic field region. At the outlet the adiabatic demagnetization of the magnetocaloric material (refrigerant) produces the "cold energy". The induced cold is described by a corre ...

Soil is a particulate material that may undergo irreversible strain as the relative positions of the constituent particles change. That irreversible behaviour may be induced not only by an external stress variation but also by temperature or suction change ...
Numerical simulation in aluminum production envolves many different topics, this paper is dedicated to some aspects of two of them. In the first part, a numerical approach for the computation of the motion of the fluids in an electrolitic cell is presented ...
