[1]Rensselaer at Hartford, Hartford, CT
[2]Pratt & Whitney, East Hartford, CT

The flow of electrically conducting fluids such as liquid metals is significantly affected by applied electric and magnetic fields. The effect has important industrial applications in metallurgy, nuclear technology and other fields. This paper described results of a series of studies ... Read More

Solar Cell Cooling and Heat Recovery in a Concentrated Photovoltaic System

M. Cozzini[1]
[1]Fondazione Bruno Kessler (FBK), Renewable Energies and Environmental Technologies (REET) Unit, Trento, Italy

Concentrated photovoltaic systems with high efficiency solar cells are being widely investigated, aiming at improving the cost-efficiency balance in the solar energy field. Different cell types are in use: e.g., high concentration triple junction cells, reaching efficiencies of the order ... Read More

Miscible Viscous Fingering: Application in Chromatographic Columns and Aquifers

S. Pramanik[1], G. L. Kulukuru[1], M. Mishra[1]
[1]Indian Institute of Technology Ropar, Rupnagar, Punjab, India

When a less viscous fluid displaces a more viscous one in a porous medium or Hele-Shaw cell, the interface between the two miscible fluids does not remain flat and deforms into fingers growing in time [1]. It occurs due to the faster movement of less viscous fluid than the more viscous ... Read More

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 ... Read More

Fluid-Structure Interaction of a Double Curvature Arch Dam Under Seismic Loading by the Application of Added Mass Technique and Acoustic Elements

R. Manikandan[1], P. Sultana[1]
[1]National Institute of Technology Silchar, Silchar, Assam, India

Fluid Structure Interaction (FSI) plays an important role in the seismic analysis and the design of Hydraulic structures. In this study, the acoustic finite element model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream ... Read More

Current Density Distribution for a Full Scale Industrial Alluminization Process

A. Giaccherini [1], S. Martinuzzi [2], E. Berretti [1], A. De Luca [3], A. Lavacchi [4], S. Caporali [2], M. Innocenti [3]
[1] Chemistry Department, University of Firenze, Firenze, Italy
[2] Consorzio INSTM, Firenze, Italy
[3] Chemistry Department, University of Firenze, Firenze, Italy
[4] Institute of Chemistry of Organometallic Compounds, CNR, Firenze, Italy

Respect to the previous approaches, in this communication the electrochemical and chemical kinetics as well as the transport phenomena, were modelled at very high level of theory, taking into account all the parameters affecting the galvanic process, including turbulent convection ... Read More

Fracture-Matrix Flow Partitioning and Cross Flow: Numerical Modeling of Laboratory Fractured Core Flood

R. Sanaee[1], G.F. Oluyemi[1], M. Hossain[1], B.M. Oyeneyin[1]
[1]Robert Gordon University, Aberdeen, United Kingdom

The contrast between hydro-mechanical behavior of the rock matrix and fracture network systems results in flow partitioning between fracture and matrix systems which is affected by the In-situ stress regime. Fracture flow, Darcy law and free and porous media flow physics interfaces of ... Read More

Equation Based Heat and Mass Transfer in Porous Media

S. Pemberton[1], K. Ekici[1], R. Arimilli[1]
[1]The University of Tennessee, Knoxville, TN, USA

Perspiration during intense physical activity is an essential part of human thermoregulation. Clothing affects the cooling rate of the body. Heat and water vapor are coupled through evaporation and transported through the fabric. A model of the above system was developed for fabrics of ... Read More

Numerical Modeling of a Microtubular Solid Oxide Fuel Cell Using COMSOL Multiphysics®

P. Pianko-Oprych[1], E. Kasilova[1], Z. Jaworski[1]
[1]West Pomeranian University of Technology, Faculty of Chemical Technology and Engineering, Szczecin, Poland

Micro-tubular Solid Oxide Fuel Cells (mSOFC) are attracting more and more interest as new generation of energy conversion devices. Although commercial applications still suffer from high costs, there is a need for further improvement of the cell performance, durability and start-up. To ... Read More

Development of Hybrid "Fluid Jet / Float" Polishing Process

Anthony Beaucamp[1]
Y. Namba[2]

[1]Zeeko LTD, Coalville, Leicestershire, UK
[2]Chubu University, Kasugai, Aichi, Japan

On one hand, the "float polishing" process consists of a tin lap having many concentric grooves, cut from a flat by single point diamond turning. This lap is rotated above a hydrostatic bearing spindle of high rigidity, damping and rotational accuracy. The optical surface thus floats ... Read More
