Study Of Inhomogeneity In Large Format Li-Ion Cells With Different Multiphysics Models

S. Arnold [1]
[1] TUM CREATE - Energy Storage Systems, Singapore

Large format Li-Ion battery cells (LIBC), often employed in electric vehicles (EV), show notable gradients in current and temperature distribution. This inhomogeneity can influence the cell’s safety and accelerate battery aging. It is, however, difficult to determine the local ... En savoir plus

Chaotic Behavior of the Airflow in a Ventilated Room

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

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been ... En savoir plus

I .F. Melikhov [1], A. S. Amosov [1], S. A. Chivilikhin [2],
[1] Corning Scientific Center, Saint Petersburg, Russia
[2] ITMO University, Saint Petersburg, Russia

Ultrasonic levitation is a novel technology for contactless handing of various objects. It is already used in various manufacturing processes where it is important to keep untouched surface. In this paper we introduce a model of so-called near-field ultrasonic levitation which allows ... En savoir plus

Acoustic Wave Propagation in Water Filled Buried Polyethylene Pipes

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). ... En savoir plus
