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

Comparison of Flow Patterns of Different Stents Within a Simulated Disease Model

Ang Zhi Ting [1],
[1] National University of Singapore, Singapore

With increasing awareness of coronary diseases, much research has been put into the effectiveness and benefits a coronary stent can bring to a patient with a diseased coronary artery. However, current research does not fully address the effects of restenosis on the vessel, given that it ... En savoir plus

Reactive Transport Modeling of CO2 in Carbonate Rocks: Single Pore Model

P. Agrawal [1], J. Koskamp [1], A. Raoof [1], M. Wolthers [1],
[1] Utrecht University, Utrecht, The Netherlands

Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the ... 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

Entropic Evaluation of Dean Flow Micromixers

P. S. Fodor[1], M. Kaufman[1]
[1]Cleveland State University, Cleveland, OH, USA

In this work we investigate computationally the use of spiral channels at Reynolds numbers from 25 to 900 as a mixing structure (Figure 1) using COMSOL Multiphysics, the CFD Module, and the Chemical Species Transport physics. In this system, the centrifugal forces experienced by the ... 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

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

Research and Development of Multiphysics Models in Support of the Conversion of the High Flux Isotope Reactor to Low Enriched Uranium Fuel

The findings presented in this report are results of a five-year effort led by the Research Reactors Division (RRD) of the Oak Ridge National Laboratory (ORNL), which is focused on research and development toward the conversion of the High Flux Isotope Reactor (HFIR) fuel from high ...

Design, Simulation, and Fabrication of Thermal Angular Accelerometers

H. Alrowais [1],
[1] School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA

This abstract introduces a sensor design for detecting angular acceleration in a single plane using thermal convection. The working principal of the device is based on probing temperature profile changes along a micro-torus caused by angular acceleration. By properly choosing the ... En savoir plus

Fluid Flow Analysis For Cross-Flow Around Four Cylinders Arranged In A Square Configuration

A. Dutta, P. Goyal, R.K. Singh, and K.K. Vaze
Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Cross-flow around a group of cylinders is a very common phenomenon in engineering, such as flow around heat exchanger tube arrays. The cross-flow-induced vibration might cause a reduction of equipment life and might even lead to the occurrence of severe accidents. Hence, it is necessary ... En savoir plus
