Calculation of Cable Parameters for Different Cable Shapes

H. Lorenzen[1], J. Timmerberg[1], and S. Mylvaganam[2]
[1]Department of Electrical Engineering, UAS OOW, Wilhelmshaven, Germany
[2]Department Technology/Engineering, Telemark University College, Porsgrunn, Norway

Efforts involving simulation of transmission line networks necessitate the accurate values of the parameters of the lines. In this paper, as an attempt in estimating such parameters, the parameters of high voltage asymmetric power lines are calculated. In the process of estimation, the ... En savoir plus

Effect of Proximity on the Thermal Rating of a Single Power Cable in Ventilated Tunnels

[2] University of Valenciennes, Valenciennes, France
[3] EDF CIST, Paris, France

Power transmission through power cables installed in ventilated tunnels has been increasingly used worldwide and offers a complex thermal environment. These cables are placed on supports or fixed close to the tunnel walls. Established correlations currently in use have been deduced from ... En savoir plus

Design of a Self-Recharging Untethered Mobile Inspection Tool inside a Pipeline

W. Chalgham [1], A. C. Seibi [1],
[1] University of Louisiana at Lafayette, Lafayette, LA, USA

Pipeline inspection tools present some limitations related to power supply which require recharging after each operation. Using batteries or tethered tools make the duration to inspect any pipeline very limited and time consuming. This paper aims at designing a spherical self-recharging ... En savoir plus

Numerical Simulation of Electrostatic Charging Droplets in Microfluidic Devices

S. Yao[1], H. Zhou[1]
[1]HKUST, Hong Kong, China

In this paper, the mechanism of charging process was simulated and analyzed. The simulation was conducted using COMSOL Multiphysics® software, based on the laminar two-phase flow level-set interface coupling with the electrostatic interface. Meanwhile, different parameters (such as the ... En savoir plus

Glass Transition of ABS in 3D Printing

M. Rahman [1], N. R. Schott [2], L. K. Sadhu [3],
[1] North South University, Dhaka, Bangladesh
[2] Department of Plastics Engineering, University of Massachusetts - Lowell, Lowell, MA, USA
[3] IRays Teknology Ltd., Dhaka, Bangladesh

In a commercial 3D printer head, plastic ribbon passes through a hot nozzle of an extruder to dispense liquid plastic droplets to construct the model. In this paper a 2D axisymmetric model of a 3D head is considered to study the secondary transition change from below the glass ... En savoir plus

Implementation of COMSOL Multiphysics® in Simulink® S-Functions, Revisited

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

COMSOL Multiphysics® has standard facilities to export models to SimuLink®. Normally, the standard export works well if the solvers, available in SimuLink, can handle the problem. However, if a model in COMSOL Multiphysics® needs special solvers, for example airflow or other non-linear ... En savoir plus

Simulação Fluidodinâmica de um Digestor Contínuo para Produção de Celulose.

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 ... En savoir plus

Effect of Magnetic Field on MR-Fluid in Ball End Magnetorheological Finishing

H. Garg[1], V. S. Negi[1], A. S. Kharola[1], R. Sharma[1]
[1]CSIR - Central Scientific Instruments Organization, Chandigarh, India

Magnetorheological Finishing (MRF) is one of the precision finishing processes in which magnetic field is used to drive abrading forces for Finishing 2D and complex 3D surfaces. In this paper, Ball End Magnetorheological Finishing (BEMRF) has been analyzed for fluid behaviors under the ... En savoir plus

Numerical Modeling of 3D Electrowetting Droplet Actuation and Cooling of a Hotspot

M. M. Nahar [1], H. Moon [1], G. S. Bindiganavane [1], J. Nikapitiya [1]
[1] Department of Mechanical and Aerospace Engineering, University of Texas - Arlington, Arlington, TX, USA

Electrowetting on Dielectric (EWOD) is a versatile tool for performing basic operations in Digital Microfluidic Systems. In EWOD, surface tension between a liquid droplet and solid substrate is modulated by applying voltage to an electrode and a hydrophobic surface is transformed into a ... En savoir plus
