Numerical Investigation of Strouhal Frequencies of Two Staggered Bluff Bodies

Eswaran M[1], P. Goyal[1], Anu Dutta[1], G.R. Reddy[1], R. K. Singh [1], K.K. Vaze[1]
[1]Bhabha Atomic Research Centre, Mumbai, India

A 2-D unsteady viscous flow around two cylinders is studied by numerical solutions of the unsteady Navier-Stokes equations with a finite element formulation using COMSOL Multiphysics®. The results of a numerical investigation of the Strouhal frequencies of two identical, stationary, ... En savoir plus

An MHD Study of the Behavior of an Electrolyte Solution Using 3D Numerical Simulation

L. P. Aoki[1], H. E. Schulz[1], M. G. Maunsell[1]
[1]University of São Paulo, São Carlos, SP, Brazil

This article considers a closed water circuit with square cross section filled with an electrolyte fluid. The conductor fluid was moved using an electromagnetic pump, in which a permanent magnet generates a magnetic field and electrodes generate the electric field in the flow. Thus, the ...

Modelling of SiC Chemical Vapour Infiltration Process Assisted by Microwave Heating

G. Maizza[1] and M. Longhin[1]
[1]Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... En savoir plus

Energy Harvesting from Variation in Blood Pressure through Deformation of Arterial Wall using Electro-magneto-hydrodynamics

A. Pfenniger[1], V.M. Koch[2], A. Stahel[2], and R. Vogel[1]
[1]ARTORG Cardiovascular Engineering, University of Bern, Bern, Switzerland
[2]Bern University of Applied Sciences, Engineering and Information Technology, Biel, Switzerland

The present project aims at modelling a generator that harvests energy from the variation in blood pressure by exploiting the motion of the arterial wall between the diastolic and systolic phase of the cardiac cycle. The concept is to use a highly electrically conductive fluid, which is ... En savoir plus

Numerical Model For Rocking Of Mono-Pile In A Porous Seabed

D-S. Jeng, X. Luo, and J. Zhang
Division of Civil Engineering, University of Dundee, Dundee, Scotland, UK

Offshore wind and wave energy industries have developed considerably in the last two decades. Most offshore energy structures used in the existing projects are mono-piles in shallow water due to simplicity of installations, design and control. Numerous research for the design and ...

Microfluidic Systems for Cell Growth and Cell Migration Studies

M.Dimaki[1], P. Shah[1], D. Kwasny[1], J. Lange Moresco[2], and W. E. Svendsen[1]
[1]Department of Micro- and Nanotechnology, Technical University of Denmark, Lyngby, Denmark
[2]Sunstone Capital, Copenhagen, Denmark

Lab-on-a-chip devices for cell culturing are becoming imperative in order to satisfy the needs for point-of-care or decentralized laboratory testing. Towards that goal we have developed miniaturized membrane based cell culture chambers for use within the field of chromosome analysis. The ... En savoir plus

Computationally Assisted Design and Experimental Validation of a Novel ‘Flow-Focussed’ Microfluidics Chip for Generating Monodisperse Microbubbles

Whilst initially developed as a diagnostic aid to improve echogenicity in ultrasound imaging, gas-filled lipid microbubbles are now emerging as a next generation \'theranostic\' tool in the medical arena. Here, their therapeutic potential has now been realized through their unique ... En savoir plus

Applicability of the Fracture Flow Interface to the Analysis of Piping in Granular Material

S. Bersan[1], C. Jommi[2], A. Koelewijn[3], P. Simonini[1]
[1]University of Padua, Padua, Italy
[2]Delft University of Technology, Delft, The Netherlands
[3]Deltares, Delft, The Netherlands

Piping is a kind of internal erosion that occurs under water retaining structures lying on a sandy soil. In an attempt to reproduce the growth of erosion channels in sand, a small scale physical model has been set up in the laboratory and a finite element model that reproduces the ... En savoir plus
