When Precise Numerical Predictions Come to the Rescue of Liquid Lubrication

J. D. Wheeler [1], V. Bruyere [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Whereas some bearings designed in the 19th century are still working properly nowadays, some others which were recently designed encountered premature failures. Tribological applications, such as journal bearings or rolling element bearings, are generally ruled by complicated ... En savoir plus

Advancements in Carbon Dioxide and Water Vapor Separations Using COMSOL

J. Knox[1], K. Kittredge[1], R.F. Coker[1], R. Cummings[1], C.F. Gomez[1]
[1]NASA - Marshall Space Flight Center, Huntsville, AL, USA

“NASA\'s Advanced Exploration Systems (AES) program is pioneering new approaches for rapidly developing prototype systems, demonstrating key capabilities, and validating operational concepts for future human missions beyond Earth orbit” [1]. Under the new Atmosphere Revitalization ... En savoir plus

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 ... En savoir plus

Numerical Study of Microfluidic Fuel Cell Performance

A. E. Khabbazi[1], A.J. Richards[1], and M. Hoorfar[1]
[1]School of Engineering, UBC Okanagan, Kelowna, BC Canada, Canada

Using COMSOL Multiphysics 3.5, a numerical model has been developed to determine the effect of the channel geometry and electrode configuration on cell performance based on polarization curves. The Butler-Volmer equation was implemented to determine the reaction rates at the electrodes. ... En savoir plus

Coupling Miscible Flow and Geochemistry for Carbon Dioxide Flooding into North Sea Chalk Reservoir

B. Niu[1], W. Yan[1], A.A. Shapiro[1], and E.H. Stenby[1]

[1]Department of Chemical and Biochemical Engineering, Technical University of Denmark, Kgs. Lyngby, Denmark

As an effective method to cope with green-house gas emission, and to enhance oil recovery, injection of carbon dioxide into oil reservoirs has obtained increasing attentions. The flooding process involves complex phase behavior among oil, brine and CO2, and geochemical reaction between ... En savoir plus

A Semplified Model for the Evolution of a Geothermal Field

L. Meacci[1], A. Farina[1], F. Rosso[1], I. Borsi[1], M. Ceseri[1], and A. Speranza[1]

[1]Dipartimento di Matematica U. Dini, Università degli Studi di Firenze, Firenze, Italy

The problem is to understand how a geothermal field can evolve from a water dominated state into a vapor dominated one. A first answer to this question is given by a simplified mathematical model of the dynamics of a geothermal field in which the geothermal fluid is entirely composed by ... En savoir plus

Design and Simulation of 3D Printed Check Valves Using Fluid-Structure Interaction

A. M. Melvin [1], T. J. Roussel [1],
[1] Department of Bioengineering, J.B. Speed School of Engineering, University of Louisville, Louisville, KY, USA

Passive, one-way valves, also known as check valves, while common at the macro scale, are an essential microfluidic feature that facilitate flow rectification. These structures are also commonly used in reciprocating micropump configurations to control flow. Their operation can be ... En savoir plus

Comparison of an Analytical and Numerical Solution for the Landmine Detection Problem

M. Mattingly[1], K. McIlhany[2], and R. Malek-Madani[3]

[1]Applied Research Laboratory, The Pennsylvania State University, University Park, PA, USA
[2]Physics Department, United States Naval Academy, Annapolis, MD, USA
[3]Mathematics Department, United States Naval Academy, Annapolis, MD, USA

Acoustic landmine detection is accomplished using a loud speaker as an airborne source to generate low-frequency waves that enter the soil at a certain incident angle. At a specific frequency, the landmine will "vibrate" at resonance, imparting a certain velocity on the soil particles ... En savoir plus

On the Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption

J. Knox [1],
[1] Marshall Space Flight Center - NASA, Huntsville, AL, USA

This work examined in detail the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer information from experimental breakthrough data and the consequences that may arise when doing so based on using a 1-D axially ...
