Numerical Investigation of Mass Transfer with Two-Phase Slug Flow in a Capillary

W. Han, and B.H. Dennis
University of Texas, Arlington, TX, USA

The multiphase flow of two immiscible liquids in a microchannel was investigated numerically. A Y-shape micromixer was designed to produce a pattern of slugs from the flowing liquids. The mass transfer characteristics of this flow pattern are of primary interest in this study. A simple ... En savoir plus

Boundary Element Technique in Petroleum Reservoir Simulation

M. Liu, and G. Zhao
University of Regina
Regina, SK
Canada

Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM). It is proven to be able to provide a computationally ... En savoir plus

A Dynamic Electrowetting Simulation using the Level-Set Method

B. Cahill[1], A. Giannitsis[1], G. Gastrock[1], M. Min[1,2], and D. Beckmann[1]
[1]Institut für Bioprozess- und Analysenmesstechnik e.V., Heiligenstadt, Germany
[2] Department of Electronics, Tallinn University of Technology, Tallinn, Estonia

Electrowetting occurs with the electrical control of the surface wetting properties through the application of an electric potential. A simulation of electrowetting driven droplet dynamics is performed using the COMSOL Multiphysics level-set method for a sessile droplet and for a ... En savoir plus

Simulation of Oxygen Transport and Cellular Uptake in a Microphysiological System

M. J. Hancock¹, Felipe T. Lee-Montiel², Caleb S. Lee², Kevin E. Healy²
¹Veryst Engineering, LLC, Needham, MA, USA
²University of California, Berkeley, CA, USA

Microphysiological systems (MPS) combine microfluidics, MEMS, and biotechnology techniques to mimic human organ function in vitro. Such devices are being developed to provide better levels of tissue and organ functionality compared with conventional cell culture systems, and have great ... En savoir plus

Performance Evaluation of the 19th Century Clipper Ship Cutty Sark: A Comparative Study

C. Tonry[1], M. Patel[1], C. Bailey[1], W. Davies[1], J. Harrap[1], E. Kentley[1], P. Mason[1]
[1]University of Greenwich, London, UK

The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship [1]. One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers [2]. They ... En savoir plus

Geologic Carbon Storage: Implications of Two-Phase Flow on Injection-Induced Stress on Faults

S. Prasun [1], S. Kim [2], S. A. Hosseini [3],
[1] Louisiana State University, Baton Rouge, LA, USA
[2] Department of Civil Engineering University of Nebraska - Lincoln, Omaha, NE, USA
[3] Bureau of Economic Geology, University of Texas - Austin, Austin, TX, USA

Geologic carbon storage that involves injecting carbon dioxide (CO2) into a subsurface sequestration site provides the vital approach for reducing CO2 emissions into atmosphere and thus addressing climate change issue. One challenge associated with CO2 geologic storage is that pore ... En savoir plus

Two-Dimensional COMSOL Simulation of Heavy-Oil Recovery by Electromagnetic Heating

M. Carrizales[1], and L.W. Lake[1]

[1]The University of Texas at Austin, University Station, Austin, Texas, USA

Introducing heat to the formation has proven to be an effective way of lowering the oil viscosity of heavy oils by raising the temperature in the formation. The application of electrical energy has gained more interest during the last decade because it offers fewer restrictions for its ... En savoir plus

Effect of Interfacial Charge on the Drop Deformation under the Application of Oscillatory Electric Field.

R. Patil[1], and V. A. Juvekar[1]
[1] Department of Chemical Engineering, Indian Institute of Technology Bombay, Maharashtra

Study of interaction of drops and bubbles with electric field is important for understanding the physics involved in various physical phenomenas and industrial processes. Important applications arise in colloidal systems (Miller and Scriven, 1970), meteorology and cloud physics (Sartor, ... En savoir plus

High Temperature Process Simulation

O. Geoffroy, and H. Rouch
INOPRO, Villard de Lans, France

The crystal growth industry uses high temperature processes. To improve production efficiency, a good knowledge of thermal effects is necessary. We show in this article a methodology to get reliable data by mixing simplified models, sensitivity studies and parameters adjustments. The ... En savoir plus

Level Set Method for Fully Thermal-Mechanical Coupled Simulations of Filling in Injection and Micro-Injection Molding Process
