Influence of Air Gap Length and Cross-Section on Magnetic Circuit Parameters new

A. Polit[1], R. Jez[1]
[1]ABB Corporate Research Center, Krakow, Poland

The air gap is one of the most crucial part of magnetic circuits, especially in high-power inductors. It significantly modifies the parameters of magnetic devices by increasing the saturation current, linearizing B-H curve of magnetic circuit and causing a decreasing in the inductance. ... Read More

[1]AltaSim Technologies, LLC., Columbus, OH, USA

Computational tools based on the finite element method have been used extensively to develop solutions for elastic and elastic-plastic fracture mechanics problems. This work uses a small-scale yielding model to compare results developed from COMSOL Multiphysics® with another finite ... Read More

The Design of a Multilayer Planar Transformer for DC/DC Converter with a Resonant Inverter new

M. Puskarczyk[1], R. Jez [1]
[1]ABB Corporate Research Center, Krakow, Poland

Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis ... Read More

Dispersion Analysis in Coaxial Cables at High Frequencies

S. C. Hegde[1]
[1]VIT University, Vellore, Tamil Nadu, India

The coaxial cable is one of the most commonly used bandwidth limited signal transmission line.Dispersion is a signal distortion phenomenon which arises due to frequency dependence of phase velocity of signal components. This phenomenon was explained through time domain approach by ... Read More

Residence Time Distribution for Tubular Reactors new

L. R. de Souza Jr.[1], L. Lorenz[1]
[1]Universidade Federal do Paraná, Curitiba, Paraná, Brazil

In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal ... Read More

Numerical Modeling of P-i-N Solar Cell new

J. J. Mahakud[1], D. Sengupta[1]
[1]Institute of Technical Education & Research, Siksha 'O' Anusandhan University, Bhubaneswar, Odisha, India

Solar energy is the cleanest form of renewable energy. The most popular form of utilization of solar energy is through the use of photovoltaic cells. Currently the efficiency of available solar cells lies below 20%. To increase the efficiency, multi-junction can be used in solar cells. ... Read More

Modeling of Ultrasonic Transducers and Ultrasonic Wave Propagation for Commercial Applications Using Finite Elements with Experimental Visualization of Waves for Validation new

D. R. Andrews[1]
[1]Cambridge Ultrasonics, Over, UK

Finite element (FE) modelling of ultrasonic propagation using COMSOL Multiphysics® simulations can be used to create images of waves. Unfortunately, in time-stepping solutions, it is possible for numerical instabilities to grow large and dominate the solution adversely. Any design of ... Read More

Models of Simple Iron Cored Electromagnets new

J. Mammadov[1]
[1]University of Manchester, Manchester, UK

This report mainly discusses the implementation and results of a project proposal, “Modelling using Finite Element Methods”. The report is devoted to implementation, which is a model of an electromagnet. The software tool that is used to model the electromagnet is COMSOL Multiphysics®, a ... Read More

Acoustic Wave Propagation in Water Filled Buried Polyethylene Pipes new

T. Graf[1], T. Gisler[1], P. Sollberger[1], O. Schaelli[1]
[1]School of Engineering and Architecture, Lucerne University, Horw, Switzerland

Axisymmetric acoustic waves propagating along buried water pipes have been investigated by FEM and experimentally. Universal dispersion relations of the fundamental mode were obtained as a function of the standard dimension ratio SDR and of the material surrounding the pipe (soil, air). ... Read More
