This paper presents the design and analysis of a high power radial flux Brushless DC motor for electro-mechanical actuation system. The motor is used for driving an electro-mechanical actuator of 20 ton capacity. Surface mounted, radially magnetized permanent magnet design is mostly ... En savoir plus
Darcian and non-Darcian porous media are characterized by the porosity of medium. To capture miscible viscous fingering in both types of porous media, a new model built with COMSOL® software is presented by coupling of two different physics interfaces (hydrodynamics and transport of ...

COMSOL Multiphysics® software was used to model radial source flow in two dimensional homogeneous porous media. Two-Phase Darcy's Law (tpdl) is used to model miscible viscous fingering. Fingering patterns obtained on using different mesh are discussed. Evolution from 'flowers' to ... En savoir plus
A three-dimensional heterogeneous model of breast has been modeled with a spherical tumor of 1.5 cm. PID controller has been used to perform temperature-controlled RFA of breast tumor. The coupled effect of blood perfusion and variable conductivity during RFA has been investigated. The ... En savoir plus
Piezo buzzers, made of piezoelectric material glued on a brass plate, are usually used as signaler, but the buzzer can also be used to convert mechanical into electrical energy. If acceleration influences the buzzer, the structure is bent by its mass and a voltage can be measured between ... En savoir plus
In the last decades, the topic of microfluidic Electroosmotic Pumps (EOP) gained the attention of scientists all over the world. One of the greatest advantages of the electroosmotic pumps is the fact, that there are no moving parts. With the effect of electro osmosis, it is possible to ... En savoir plus
Modern aluminum casement windows consist of an inner and outer profile made of aluminum, which are separated by an insulating bar made of polyamide (see Figure 1). Due to the low heat conductivity of the plastic material the thermal interaction between the living space and the ... En savoir plus
INTRODUCTION The global energy infrastructure is comprised of a variety of power magnetic devices (PMDs) which include motors, generators, transformers, inductors, actuators, relays, etc. In the field of power engineering, and particularly in the design of PMDs, modern advances are ...

Introduction: Flat lenses require precise control of a phase gradient across an interface, which is enabled through the application of engineered surfaces, such as Metasurfaces [1]. Periodic arrays of plasmonic antennas have been utilized to generate this desired phase gradient, which ... En savoir plus
Due to the advantages of induction heating as a method for precise and efficient local heating, it is perfectly suited for thermal shrink fitting of a gear wheel on a shaft. In this work, a simulation model was established to study the induction heating of a gear wheel, its thermal ... En savoir plus
