COMSOL Multiphysics® has proven to be an invaluable “virtual laboratory” tool in assisting our development of a new generation of efficient analytical models describing the acoustics of highly porous fibre and foam materials. From the definition of the physical relations describing the ... En savoir plus

Two transmitting planar microcoils (TX1, TX2) and one receiving microcoil (RX) are employed as shown in Fig.1 formed in induction-balance configuration. RX-Coil is positioned in such a way to achieve primary field suppression in RX-Coil’s region. Meaning, a magnetic cavity is created in ... En savoir plus

Atmospheric-pressure plasma jets (APPJ) are devices that generate chemically reactive species and operate at atmospheric pressure and ambient temperature for a wide range of applications. Plasmas jets produce charged particles (electrons and ions), neutral metastable species, radicals, ... En savoir plus

The rapidly increasing world population will dramatically expand the future global freshwater requirements, now making lots of researchers realize the fundamental importance of developing effective desalination technologies. Hence, the emerging capacitive deionization (CDI) desalination ... En savoir plus

Modern problems of biomechanics, in particular, the problems of modeling vision correction in ophthalmology are associated with the study of the stress-strain state of shells and plates made of complex materials. These problems are essentially nonlinear in geometry and in physical ... En savoir plus

It has been well proved that hydrogen represents a harmful element for steels because it can easily embrittle them. This phenomenon is known as Hydrogen Embrittelement (H.E.) and it leads to a serious decrease in mechanical properties especially loss of ductility. The studied material is ... En savoir plus

Joule-Thomson effect describes a change of temperature in a fluid due to a sudden change of pressure under adiabatic conditions. The aim of this study is to reproduce Joule-Thomson effect when an incompressible gas flows through a narrow pipe connecting two tanks at different pressures. ... En savoir plus

Although SF6 gas is characterized by a strong global warming potential, traditionally, it has been employed universally as the dielectric insulation gas for most electrical equipment because of its excellent technical performances. With the emergence of environmental regulations for ... En savoir plus

Shape and Topology Optimization of Loudspeaker Drivers This paper illustrates the use of formal mathematical optimization techniques for engineering solutions focused towards loudspeaker drivers. Both shape and topology optimization techniques are applied, with the physics ranging ... En savoir plus

Soft robotics allows for an increased flexibility and adaptability in the field of robotics, for example increased safety with regard to human-machine systems [1]. The Pneumatic Honeycomb Network (PHN) analyzed in this paper is a constitutive element in a new approach of dynamically ... En savoir plus
