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. ...

The design satisfies all thermal and physical issues relating to the battery packs used in vehicles such as operating temperature range and volume, ... Mehr lesen

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 ... Mehr lesen

Small Scale Yielding Model for Fracture Mechanics new

K. C. Koppenhoefer[1], J. Thomas[1], J. S. Crompton[1]
[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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

CVD Graphene Growth Mechanism on Nickel Thin Films new

K. Al-Shurman[1], H. Naseem[2]
[1]The Institute for Nanoscience & Engineering, University of Arkansas, Fayetteville, AR, USA
[2]Department of Electrical Engineering, University of Arkansas, Fayetteville, AR, USA

Chemical vapor deposition is considered a promising method for synthesis of graphene films on different types of substrate utilizing transition metals such as Ni. However, synthesizing a single-layer graphene and controlling the quality of the graphene CVD film on Ni are very ... Mehr lesen

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 ... Mehr lesen

An Overview of Impellers, Velocity Profile and Reactor Design new

P. Patel[1], P. Vaidya[1], G. Singh[2]
[1]Indian Institute of Technology Bombay, Mumbai, Maharashtra, India
[2]Indian Oil Corporation Limited, Faridabad, Haryana, India

This paper presents a simulation approach to develop a model for understanding the mixing phenomenon in a stirred vessel. The mixing in the vessel is important for effective chemical reaction, heat transfer, mass transfer and phase homogeneity. In some cases, it is very difficult to ... Mehr lesen

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). ... Mehr lesen
