The Virtual Aquarium: Simulations of Fish Swimming

M. Curatolo [1], L. Teresi [2],
[1] Department of Engineering, Università Roma Tre, Roma, Italy
[2] Department of Mathematics and Physics, Università Roma Tre, Roma, Italy

Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics ... En savoir plus

High-Resolution FSI Modeling of a High-Aspect Ratio Involute Flow Channel in the HFIR at ORNL

A. I. Elzawawy [1], J. D. Freels [2], F. G. Curtis [2, 3],
[1] Vaughn College of Aeronautics and Technology, East Elmhurst, NY, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA
[3] University of Tennessee, Knoxville, TN, USA

The high flow rate within the HFIR cooling water flow channel causes the fuel plates to deflect which in turn, changes the coolant flow characteristics. This nonlinear feedback loop between the coolant and the fuel plate is the focus of the present simulation of the fluid-solid ... En savoir plus

Interaction of Microparticles in a Miniaturized Vacuum-Cleaner

I. S. M. Jimidar [1], Y. Vanderheyden [1], H. Gardeniers [2], G. Desmet [1],
[1] Vrije Universiteit Brussel, Department of Chemical Engineering, Brussels, Belgium
[2] Universiteit Twente, Mesoscale Chemical Systems MESA+, Enschede, The Netherlands

The ever-growing complexity of samples which need to be processed in e.g., environmental and biomedical/biochemical research, demand higher efficiencies of analytical techniques. Liquid chromatography (LC), mass spectrometry, among others, are analytical techniques that revolutionized ... En savoir plus

3D Acoustic-Structure Interaction of Ultrasound in Fluids for the Manufacture of Graded Materials

J. Holt [1], C. Torres-Sanchez [1], P. Conway [1], M. G. Garcia-Romero [1],
[1] The Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, Leicestershire, UK

Functionally graded materials (FGM) are those that contain chemical, phase or structural gradients. Whilst the design of functionally graded structures is well researched in areas such as shape optimisation and topology optimization, their manufacture is still in development. One ...

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

Design and Simulation of MEMS Based Piezoelectric Insulin Micro-Pump

F. Meshkinfam [1],
[1] University of Ontario Institute of Technology, Oshawa, ON, Canada

One of the most effective treatments for diabetes type 1 and 2 is the administering Insulin. The design of positive volumetric insulin pump is significantly a multiphysics problem where the volumetric change of the main pump chamber and the pumped fluid are directly coupled. We used ...

Boundary Arbitrary Lagrangian-Eulerian and Deformable Boundary Perturbation Method

J. Rivero-Rodriguez [1], B. Scheid [1],
[1] Université Libre de Bruxelles, Brussels, Belgium

Partial differential equations on unknown domains is a mathematical problem that arises in many applications. Several examples can be easily found in the dynamics of free surfaces in fluid dynamics or in fluid-structure interactions. In many situations, large deformations are encountered ... 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

Damping in Dense Gas Acoustic Structure Interaction

J. P. M. Smeulers [1], H. P. Pereboom [1], N. González Díez [1],
[1] TNO, Delft, The Netherlands

Large centrifugal compressors, which are commonly applied in the oil and gas and in the process industry, may fail due to vibrations of the impeller. These vibrations are induced by pressure pulsations in a compressor stage. These vibrations can be especially strong in so-called dense ... 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
