Biofluid-Structural Interaction in Abdominal Aortic Aneurysm for Predicting Timeline to Rupture: The Effect of Hypertension and Aorta Wall Material Properties

K. Cluff[1], H. Mehraein[1], G. Jayakumar[2]
[1]Bioengineering, Wichita State University, Wichita, KS, USA
[2]Industrial & Manufacturing Engineering, Wichita State University, Wichita, KS, USA

An abdominal aortic aneurysm (AAA) is a bulge formed in the large blood vessels that supply blood to the abdomen, pelvis, and legs. A fluid structure interaction model was developed in a 3D aortic aneurysm model, which was constructed from abdominal CT scan images. Combining medical ... En savoir plus

Air Damping Simulation of MEMS Torsional Paddle

N. Mahmoodi[1], C. J. Anthony[1]
[1]University of Birmingham, Birmingham, UK

Viscous damping has a significant effect on dynamic performance of the resonators operating within fluid. This work is aimed to find the viscous damping for MEMS torsional paddle operating in air. Interaction of moving structure with the fluid requires a complicated and challenging ... En savoir plus

A COMSOL Multiphysics® Software Analysis of Beam Tube Cooling in the High Flux Isotope Reactor of ORNL

J. D. Freels [1],
[1] Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA

Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis ... En savoir plus

Modeling of Directional Dependence in Nanowire Flow Sensor

A. Piyadasa[1,3], P. Gao[1,2,3]
[1]Department of Physics, University of Connecticut, Storrs, CT, USA
[2]Department of Materials Science & Engineering, University of Connecticut, Storrs, CT, USA
[3]Institute of Materials Sciences, University of Connecticut, Storrs, CT, USA

3D finite element analysis model has been constructed for testing the directional dependence in a novel form of nanowire array gas flow sensor. Single nanowire (p-type single crystal Silicon) model is developed using fluid structure interaction and piezoresistivity components in the MEMS ... En savoir plus

Flow Induced Oscillations of Marine Risers with Wake Interference

F. Van den Abeele, and J. Vande Voorde
OCAS N.V., J.F. Kennedylaan 3, Zelzate, Belgium

With offshore oil and gas exploration and production moving into ever deeper waters, the suspended length of marine risers (transporting hydrocarbons from the seabed to the surface) can easily exceed 3000 meters. One of the major design requirements for risers in (ultra) deep water is to ... En savoir plus

Thin Microchip Release From a Carrier Tape: Structural Mechanics and Vacuum Forces

S. Behler[1]
[1]Besi Switzerland AG, Switzerland

During semiconductor manufacturing, finished silicon microchips need to be released from a carrier tape they stick to by an adhesive. This is done by vacuum forces that (a) hold the chip flat from above and (b) pull the tape off from the chip underside. Sounds simple, but is very tricky ... En savoir plus

Modelling the Structural-Dynamics of Electrical Overhead Line Power Conductors

M. Al Aqil[1], K. Kopsidas[1]
[1]The University of Manchester, United Kingdom

As a general definition, the presence of any repeated motion after a regular interval of time is known as vibrations. The basic theory of vibrations is described by the system of forces acting on a moveable and deformable body. The natural phenomena existing in the universe such as ... En savoir plus

Modelling of a Single Cardiomyocyte Interaction with a Microcantilever Using COMSOL Multiphysics®

I. Banerjee[1]
[1]Tampere University of Technology, Tampere, Finland

: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are ... En savoir plus

Flotation Height in 'Air Hockey' Spatial Atomic Layer Deposition

J. Grasso [1], B. Willis [1],
[1] Department of Chemical and Biomolecular Engineering, University of Connecticut, Storrs, CT, USA

Atomic layer deposition(ALD) is one proven method to deposit ultra-thin films. ALD is advantageous for its atomic-level thickness control and conformity; leading to high quality films. Slow deposition rates for conventional ALD contribute to the impracticality of utilization of this ... En savoir plus

Proof of Concept and Properties of Micro Hydraulic Displacement Amplifier

R. Zhu[1], A. Malisauskaite[1], U. Mescheder [1], U. Wallrabe[2]
[1]Hochschule Furtwangen University, Furtwangen, Baden-Württemberg,Germany
[2]Institut für Mikrosystemtechnik (IMTEK), Freiburg, Baden-Württemberg, Germany

Nowadays, mathematical models have been widely applied in varies fields; especially in fluid mechanics and nonlinear material which are very complex or even not possible to be calculated using analytical methods. In this paper, a hydraulic displacement amplifier coupled with fluid ... En savoir plus
