Reduction of the engine vibration and the dynamic forces transmitting from engine to the automotive body structure has always been an important part of automotive research. Automobile engineers face the task of creating a mechanism to absorb these vibrations and provide a smooth ride. ... Read More

Methodology for Calculation Scattering Parameters in a Transmission-Line Transducer

E.J.P. Santos[1], L.B.M. Silva[1]
[1]Laboratory for Devices and Nanostructures, Departamento de Eletrônica e Sistemas, Universidade Federal de Pernambuco, Várzea, Recife, PE, Brasil

Transmission-line transducers are used for the measurement of absorption and reflection of different materials, such as: liquids, granular medium, and ground. A simplified methodology for calculation of scattering parameters of such transducers is presented. The transducer cell is ... Read More

Drug Distribution in the Human Eye

L. Murtomäki[1], T. Kainuvaara[1]
[1]University of Helsinki, Helsinki, Finland

Drug therapy of the posterior segment of an eye is very challenging due to the difficult accessibility. Modern drugs often are large molecules, such as peptides, antibodies or oligonucleotides which are administrated, e.g. by intravitreous injections which requires clinical conditions. ... Read More

Numerical Calculation of the Dynamic Behavior of Asynchronous Motors with COMSOL Multiphysics

J. Güdelhöfer[1], R. Gottkehaskamp[1], A. Hartmann[1]
[1]Department of Electrical Machines and Electromagnetic Field Theory, University of Applied Sciences Düsseldorf, Düsseldorf, Germany

This paper shows how a time-dependent and non-linear simulation of the dynamic operation behavior of an induction machine is executed by means of the \"Rotating Machinery\" interface from COMSOL Multiphysics 4.2a. The two-dimensional FEM model is connected to electrical circuits by ... Read More

Dynamics of a Sessile Droplet Evaporation

G. Marinaro[1], A. Accardo[1], E. Di Fabrizio[1]
[1]Istituto Italiano di Tecnologia, Nanostructures Department, Genova, Italy

Evaporation of sessile droplets is associated with simple phenomena such as the ring-like spot left by a drying coffee droplet. Evaporation rate plays an important role on the convective motion inside the droplet. These fluxes are for example one of the factors responsible for amyloid ... Read More

Quartz Transducer Modeling for Development of BAW Resonators

L.B.M. Silva[1], E.J.P. Santos[1]
[1]Laboratory for Devices and Nanostructures, Electronics and Systems Department, Universidade Federal de Pernambuco, Recife, PE, Brasil

Transducer optimization is a key aspect for successful development and deployment of advanced sensors, especially when designing 3D structures for harsh environments. For piezoelectric transducers, plate thickness determines the operating frequency of the resonator, which is frequently ... Read More

Simulation of a Plastic Bottles Solar Collector

V. Bonetti[1]
[1]Ingegneria Senza Frontiere, DESE, Università di Pisa, Pisa, Italy

In the Andean region of Southern Peru, poverty and climate are extreme: at 4000mt asl, insolation is among the highest in the world but the temperature varies more than 30 degrees between day and night. At the community of Livitaca (Cuzco), the association “Ingegneria Senza Frontiere” is ... Read More

Numerical Simulation of Oil Recovery by Polymer Injection using COMSOL

J. Wegner[1], L. Ganzer[1]
[1]Clausthal University of Technology, Clausthal, Germany

In this paper we used COMSOL Multiphysics to model basic physico-chemical effects relevant in polymer enhanced oil recovery (EOR) such as non-Newtonian rheology of the displacing phase, permeability reduction, adsorption and salinity effects. COMSOL\'s PDE interface as well as Species ... Read More
