Rheological Behaviour of Single–Phase Non-Newtonian Polymer Solution in Complex Pore Geometry: A Simulation Approach

P. Idahosa[1], G. Oluyemi[2], R. Prabhu[2], B. Oyeneyin[2]
[1]IDEAS Research Institute/School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.
[2]School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.

One of the most important criteria for evaluating chemical enhanced oil recovery (EOR) processes that use polymers is its rheological behaviour which in turn account for other physical effects of adsorption and resistance factors during polymer-rock interactions. However, complete ... En savoir plus

A Phase Field Approach to Model Laser Power Control in Spot Laser Welding

C. Touvrey[1], V. Bruyere[2], P. Namy[2]
[1]CEA DAM, Valduc, France
[2]SIMTEC, Grenoble, France

Spot laser welding is largely used in industrial manufacturing, especially in the case of small penetration depth. Unfortunately, welded joins are often polluted by porosities. The formation of porosities depends on complex thermo-hydraulic phenomena. During the interaction, a deep and ... En savoir plus

Modeling a Resonant Near-Field Scanning Microwave Microscope (RNSMM) Probe

N. Smith[1], K. Lees[1], A. Gregory[1], R. Clarke[1]
[1]The National Physical Laboratory, Teddington, Middlesex, UK

The current drive to go beyond the state of the art in novel near field scanning microwave microscope (NSMM) metrology at the micro scale, to make them capable of traceable measurements on functional materials, has led to the development of a finite element model of the probe of a ...

Multiphysics Study into Compression Rings, Coated Against Uncoated

M. Dickinson[1,2], N. Renevier [1], J. Calderbank[2,3]
[1]The Jost Institute, School of Computing, Engineering & Physical Sciences, University of Central Lancashire, Preston, UK
[2]Racing to Research Team, School of Computing, Engineering & Physical Sciences, University of Central Lancashire, Preston, UK
[3]School of Computing, Engineering & Physical Sciences, University of Central Lancashire, Preston, UK

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. ...

Study & Modeling of 'Acoustic Matching Layers' for Ultrasound Imaging Probes Through Pulse-Echo FEM Simulation

L. Spicci[1]
[1]Esaote SpA, Florence, Italy

Ultrasound Imaging probes are specific devices that require a very detailed design of acoustic impedance match for the stack of layers that form the probe head (1,3). These are typically made of silicone rubber, special epoxy resins, polyurethanes and, of course, piezoelectric ... En savoir plus

Optimization of Acoustic Silencer for the Screw Compressor System

M. Swamy[1], L. J. van Lier[1], J. Smeulers[1]
[1]TNO, Delft, The Netherlands

In one of the screw compressor system, designed silencer was not optimal. A great challenge was the large variation in operating conditions, especially the variation of the molecular weight of the gas. There was need to optimize the silencer. This paper describes the acoustic modelling ... En savoir plus

3D Modelling of Flow Dynamics in Packed Beds of Low Aspect Ratio

F. Alzahrani[1], F. Aiouache[1]
[1]Engineering Department, Lancaster University, Lancaster, UK

This work used the 3D CFD modeling to investigate non-uniform deactivation in packed bed reactors of low aspect ratios under steady state and dynamic operations. In order to explore the effects of condition of instability on local deactivation, detailed knowledge of flow dynamics (i.e. ... En savoir plus

COMSOL Multiphysics® Based Identification of Thermal Properties of Mesoporous Silicon by Pulsed Photothermal Method

N. Semmar[1], I. El Abdouni[1], A. Melhem[1]
[1]GREMI-UMR7344, CNRS/University of Orléans, Orléans, France

The silicon is mainly known under its single-crystal shape and polycrystalline. Since a few decades, a new type of morphology is developed: the porous silicon (p-Si). Meso-porous silicon (Mp-Si) is one of promising materials for future microelectronic chips multi-functionalization ... En savoir plus

Modeling and Simulation of Membrane Contactor Employed to Strip CO2 from Rich Solvents via COMSOL Multiphysics®

N. Ghasem[1], M. Al-Marzouqi[1], N. A. Rahim[1]
[1]United Arab Emirates University, Al-Ain, United Arab Emirates

A mathematical model is developed for the stripping of CO2 from rich solvent. The rich solvent (aqueous NaOH) is used in CO2 absorption from natural gas through gas-liquid hollow fiber membrane contactor. The polyvinylidene fluoride (PVDF) hollow fiber membrane was fabricated via ... En savoir plus

3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use as Trapped Field Magnets

M. Ainslie[1], J. Zou[1], D. Hu[1], D. Cardwell[1]
[1]Department of Engineering, University of Cambridge, Cambridge, UK

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... En savoir plus
