Laminar Fluid Flow and Heat Transfer Studies of an Electrical Conducting Fluid Subject to Combined Electric and Magnetic Fields

E. Gutierrez-Miravete[1], T. DePuy[2], and X. Xie[2]
[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

Finite Element Modeling of the Stress Field in a Cell-Seeded Microchannel

G. Zhu, and Y. Li
Lawrence Technological University, Southfield, MI, USA

Fluids used in biomedical microelectromechanical systems (BioMEMS) devices often exhibit very different flow behavior from those in bulk solutions, which in turn affects the behavior of cells and biomolecules in the device. In this work, we investigate an integrated microfluidic system ... 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

Modelling Heat and Mass Transfer in Microreactor for Methanol to Hydrocarbons

P. A. Delou [1,3], V. Degirmenci [2,3],
[1] Universidade Federal do Rio de Janeiro, Rio de Janeiro, RJ, Brazil
[2] University of Warwick, Coventry, United Kingdom
[3] Queen’s University Belfast, Belfast, United Kingdom

Recently, increasing availability of natural gas, due to the shale gas, raises the attention to the conversion of methane. Methanol-to-Hydrocarbons reaction (MTH) plays an important role in this route where methanol synthesized through syngas is converted into hydrocarbons, such as ... 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

Modeling Ferrofluid Flow in an Annular Gap Moving with Reciprocating Shaft

Y. He[1], R. Nilssen[1]
[1]Department of Electric Power Engineering, Norwegian University of Science and Technology, Trondheim, Norway

Ferrofluids have been successfully used in the seals for rotary shafts, but few studies focus on the reciprocating motion seals. Since the completely different operational regimes, previous experiences on the rotary motions could not be directly applied on the cases for reciprocating ... 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

Seeding Distribution in the Channel of a Cell Culture Vessel

J. Brcka [1], K. Kagawa [2], S. Ozaki [2], Y. Oshima [3], G. Zhang [4],
[1] Tokyo Electron U.S. Holdings, Inc., Austin, TX, USA
[2] Tokyo Electron, Technology Development Center, Chuo-ku, Kobe, Japan
[3] Tokyo Electron Europe LTD, Stem Cell Technology Centre, Stevenage, United Kingdom
[4] Clemson University, Rhodes Engineering Research Center, Clemson, SC, USA

Conventional cell culture (CC) techniques are advancing significantly with a trend towards a mass production. While plating density (number of cells per volume of culture medium) plays a critical role for some cell types, the initial distribution of these cells is affected by the actual ... Read More
