[1]Lynntech, Inc., College Station, Texas, USA
[2]Micro Nano Devices and Systems (MiNDS) Laboratory, Department of Electrical Engineering, University of Texas at Dallas, Texas, USA

A portable device that can identify protein and peptides real time in complex biological systems such as human bodily fluids reliably and accurately is in high demand to properly diagnose and treat medical conditions. Lynntech has developed an innovative Polydimethylsiloxane (PDMS) based ... 詳細を見る

Transient Simulation of a Naturally Ventilated Façade in a Mediterranean Climate

C. Balocco[1]
[1]Dipartimento di Energetica “Sergio Stecco”, Università degli Studi di Firenze, Firenze, Italy

Energy performances and building energy quality can be achieved by high performance envelopes. In this paper the thermal performance of a naturally ventilated façade, applied to a traditional wall, widely used in existing buildings, was investigated by a transient simulation. A ... 詳細を見る

Helium Two-Phase Flow in a Thermosiphon Open Loop

B. Baudouy[1] and F. Visentin[1]
[1]CEA, Irfu, SACM, Gif-sur-Yvette, France

The construction of high magnetic field superconducting coils requires the use of low temperature superconductors that must be cooled down to liquid helium temperature (4.2 K). Natural two-phase convection loops, i.e. thermosiphon loop, are used as cooling system for large ... 詳細を見る

An Analysis of Skimboard Hydrodynamics

N.D. Barnett[1], and E. Gutirrez-Miravete[2]
[1]General Dynamics-Electric Boat, Kingston, Rhode Island, USA
[2]Rensselaer at Hartford, Hartford, Connecticut, USA

This paper report on a study of the hydrodynamics of skimboards and surfboards using the computational fluid dynamics (CFD) module in COMSOL. The study analyzes the flow in a thin water layer underneath a skim board in a 2-D Cartesian coordinate. Three different sets of boundary ... 詳細を見る

Helical Coil Flow: A Case Study

M. Cozzini[1]

[1]Renewable Energies and Environmental Technologies Research Unit, Fondazione Bruno Kessler, Povo, TN, Italy

Stationary flow configurations in curved pipes constitute an important subject from both the theoretical and the practical point of view. A typical application concerns the calculation of secondary flow effects on the thermal efficiency of heat exchangers. Motivated by a similar problem, ... 詳細を見る

Modeling Contact Line Dynamics in Evaporating Menisci

J. Plawsky[1], A. Chatterjee[1], and P.C. Wayner Jr.[1]
[1]Department of Chemical and Biological Engineering, Rensselaer Polytechnic Institute, Troy, New York, USA

The Constrained Vapor Bubble is a fundamental fluid mechanics experiment that is scheduled to run aboard the International Space Station starting in August 2009. The experiment is focused on looking at evaporation and condensation processes at the contact line, where vapor, liquid and ... 詳細を見る

An Analysis of Heat Conduction with Change of Phase with Application to the Solidification of Copper

J. Michalski[1], and E. Gutirrez-Miravete[2]
[1]Hamilton-Sundstrand
[2]Rensselaer at Hartford, Hartford, Connecticut, US

The goal of this study was to determine the possibility of using the finite element in COMSOL Multiphysics program to obtain a high accuracy solution to a moving boundary problem, specifically, the solidification of copper. A one-dimensional geometry in Cartesian coordinates was used to ... 詳細を見る

Laminar Thermal Mixing in Coating Flows

A. Haas[1], M. Scholle[1], A. Aksel[1], H.M. Thompson[2], R.W. Hewson[2], and P.H. Gaskell[2]

[1]Department of Applied Mechanics and Fluid Dynamics, University of Bayreuth, Bayreuth, Germany
[2]School of Mechanical Engineering, University of Leeds, Leeds, United Kingdom

Heat transfer in a plane shear flow configuration consisting of two infinitely long parallel plates is considered. In laminar flows over undulated substrates eddies can be generated due to the kinematical constraints. A closed form analytical solution for the velocity field, based on ... 詳細を見る
