Ubiquitous, unobtrusive wearable computing has tremendous potential for impacting many applications including medical, personal entertainment and surveillance. Advances in the underlying technology have allowed for consistent reduction in the size and weight of emerging solutions, with increasing subsystem integration. A key component for the realisation of these systems is the short and long ...

I. Neitzel [1], R. Kreczkiuski [1],
[1] FATEB, Telemaco Borba, Paraná, Brasil

A obtenção de polpa celulósica antecede a produção de papel e envolve a separação das fibras da madeira mediante a utilização de energia mecânica, térmica, química ou a combinação desses processos. Esta operação é realizada em um reator, tubular, cilíndrico e vertical (tipicamente 6 m de diâmetro e 50 m de altura), denominado genericamente de digestor. A madeira é alimentada pelo topo na forma ...

ICP phenomenon has been widely used for fabricating microfluidic devices of pre-concentration, micromixing and desalination. However, theoretical research and simulation of ICP have not been carefully dealt with. We provide a multiphysics simulation of a DC-ICP device based on improved numerical settings in this work.

Control of Systems Modeled by COMSOL Multiphysics® as Distributed Parameter Systems

[1]Institute of Automation, Measurement and Applied Informatics of Slovak University of Technology, Bratislava, Slovak Republic

In systems and control theory dynamical systems described by partial differential equations are known as distributed parameter systems. So for modeling and dynamical analysis of distributed parameter systems wide possibilities are offered by COMSOL Multiphysics® based on numerical solution of sets of partial differential equations by finite element method. Paper presents actual possibilities ...

A Novel FEM Method for Predicting Thermoacoustic Combustion Instability

G. Campa[1] and S.M. Camporeale[1]
[1]DIMEG, Politecnico di Bari, Bari, Italy

Modern gas turbines suffer of the phenomenon of combustion instability, also known as “humming”. The main origin of the instability is considered to be related to the interaction between acoustic waves and fluctuations of the heat released by the flame. This paper presents a novel numerical method in which the governing equations of the acoustic waves are coupled with a flame heat ...

Finite Element Analysis of an Enzymatic Biofuel Cell: The Orientations of a chip inside a blood artery

C. Wang[1], Y. Parikh[1], Y. Song[1], and J. Yang[1]
[1]Mechanical & Materials Science Engineering, Florida International University, Miami, Florida, USA

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery such that the mass transport of glucose around all the micro-electrodes can be improved and hence output ...

Multiphysics Modelling of a Micro Valve

F. Bircher[1] and P. Marmet[1]

[1]Institute of Print Technology, Bern University of Applied Sciences, Burgdorf, Switzerland

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the electromagnetics, the electronics (including the control of the process), the mechanics and the fluidics with respect to ...
