[3]TU Darmstadt, Department of Electrical Energy Conversion, Darmstadt, Germany

Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... Mehr lesen

Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording

J. Bennington[1]
[1]Queen's University Belfast, Belfast, Northern Ireland, UK

A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... Mehr lesen

The Simulation of Electric Field Distribution in Electrospinning Process

Y. Zheng[1], B. Xin[2]
[1]Donghua University, Shanghai, China
[2]Shanghai University of Engineering Science, Shanghai, China

The electric field plays a very important role in the electrospinning process, which needs to be seriously considered in the electrospinning configuration developing. High voltage involved in electrospinning process leads to difficulty in measuring the electric field. Numerical ... Mehr lesen

Numerical Study on the Acoustic Field of a Deviated Borehole with 2.5D Method

L. Liu[1], W.J. Lin[1], H.L. Zhang[1]
[1]State Key Laboratory of Acoustics, Institute of Acoustics, Chinese Academy of Sciences, Beijing, China

In this paper, we use the PDE interface of COMSOL Multiphysics® software to implement the 2.5D frequency wave-number domain method to investigate the wave propagation in a deviated borehole penetrating a transversely isotropic formation. A convolutional perfectly matched layer is ... Mehr lesen

Finite Element Modeling of Vasoreactivity Using COMSOL Multiphysics® Software

J. Parikh[1], A. Kapela[1], N. Tsoukias[1]
[1]Biomedical Engineering Department, Florida International University, Miami, FL, USA

Localized calcium events in the endothelial cells (EC) can modulate smooth muscle cell (SMC) calcium (Ca2+) and membrane potential dynamics through release of endothelium derived hyperpolarizing and relaxing factors. Ca2+ levels in the smooth muscle cell (SMC) determine its contractile ... Mehr lesen

Hydrodynamics of Lake Victoria: Vertically Integrated Flow Models in COMSOL Multiphysics® Software

S. Paul[1], R. Thunvik[1], D. D. Walakira[2], J. Mango[2], J. Oppelstrup[3], R. Wait[4]
[1]The Royal Institute of Technology, Stockholm, Sweden
[2]Makerere University, Kampala, Uganda
[3]COMSOL AB, Stockholm, Sweden
[4]Uppsala University, Uppsala, Sweden

Lake Victoria is the largest tropical lake in the world and is very important for environment and economy in East Africa. The hydrodynamic processes in the shallow (40-80 m deep) water system are unique due to its location at the equator which makes Coriolis effects noticeable also for ... Mehr lesen

Temperature Gradients Controlled Broadband Acoustic Omnidirectional Absorber

F. Qian[1], L. Quan[1], X. Liu[1]
[1]Institute of Acoustics and School of Physics, Nanjing University, Nanjing, China

Previous research into acoustic omnidirectional absorber (AOA) has shown the feasibility of forming acoustic black hole to guide the incident wave into the central absorptive cavity. However, major restrictions to practical applications exist due to complexity of designing metamaterials ... Mehr lesen

Sensitivity of the Compression-Softening Effect to Mesh Imperfections in Compressed Flexures

S. Saha[1], A. Ramirez[1], C. DiBiasio[2], M. Culpepper[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA
[2]Charles Stark Draper Laboratory Inc., Cambridge, MA, USA

Introduction: Flexures are low-cost bearings that are capable of providing motion guidance with high repeatability and low friction (Figure 1). However, applications of flexure bearings are often limited by their low range. This is because motion guidance in flexures is provided by ... Mehr lesen
