Navier-Stokes Solutions for Flow and Transport in Realistic Porous Media

N. Abdussamie
American Bureau of Shipping, Tripoli, Libya

This paper illustrates how to set up and solve a two-dimensional flow problem having dimensions of 640 x 320 micro-meter using the Navier-Stokes equations with the help of COMSOL Multiphysics solver. The principle of our pore-scale modeling approach is composed of two steps. The first ... En savoir plus

A Multiphysics Approach to the Modeling of Biological Prosthetic Heart Valves

A. Avanzini[1], D. Battini[1], M. Berardi[1]
[1]Università degli Studi di Brescia, Brescia, Italy

The complex behavior of biological prosthetic heart valves was simulated. A multiphysics computational approach was adopted using different modules of COMSOL Multiphysics: the LiveLink(TM) interface was used to exchange the valve geometry with CAD, Structural Mechanics Module to set ...

Gravitational Collapse of Rectangular Granular Piles

M.H. Babaei[1], T. Dabros[2], S.B. Savage[3]
[1]Ocean, Coastal, and River Engineering, National Research Council of Canada, Ottawa, ON, Canada
[2]Natural Resources Canada, CanmetENERGY, Devon, AB, Canada
[3]Department of Civil Engineering & Applied Mechanics, McGill University, Montreal, QC, Canada

In this study, the dam-break type two-dimensional gravitational collapse of rectangular granular piles in air was numerically studied. The frictional behavior of the material was based on the von-Mises model with the Mohr-Coulomb yield surface leading to pressure and strain-rate ... En savoir plus

Fluid Flow Behavior in Steady and Transient Force Medical Injection Systems

E. Gutierrez-Miravete [1], T. Langley [2],
[1] Rensselaer Polytechnic Institute - Hartford, Hartford, CT, USA
[2] Rensselaer Polytechnic Institute, Troy, NY, USA

Syringes were first conceptualized in 1650, but were invented in 1853 by Dr. Alexander Wood. As of 2011, nearly 8 billion syringes are used each year in the United States for medical purposes (not including veterinary services). These syringes are used for diseases like diabetes, ...

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 ... En savoir plus

Computational Analysis of Metal Hydride Reactor for Thermal Energy Storage

Aswin N. [1], Pradip Dutta [1], S. Srinivasa Murthy [2],
[1] Department of Mechanical Engineering, Indian Institute of Science, Bangalore, Karnataka, India
[2] Interdisciplinary Centre for Energy Research, Indian Institute of Science, Bangalore, Karnataka, India

Metal hydride based thermal energy storage systems belong to the category of heat storage systems which rely on reversible thermo-chemical reactions to store and release heat. Specifically, these systems utilize metal/alloy hydride decomposition (endothermic) and formation (exothermic) ... En savoir plus

Modeling Approach to Facilitate Thermal Energy Management with Phase Change Materials (PCM)

D. Rubinetti [1], D. A. Weiss [1], A. Chaudhuri [2], D. Kraniotis [2],
[1] Institute of Thermal and Fluid-Engineering, University of Applied Sciences and Arts Northwestern Switzerland
[2] Department of Civil Engineering and Energy Technology, Oslo Metropolitan University, Norway

Thermal energy storage systems receive notable attention within the framework of energy management due to their ability of bridging thermal energy demand and supply, thus leading to an overall efficiency increase. The key component in such systems are materials which convert ... En savoir plus

The Effect of Microchannel Geometry on Dispersing Solute Asymmetries

A. Taylor [1], D. Harris [1],
[1] Brown University, Providence, RI, USA

Within the field of microfluidics, scientists and engineers have found ways to manipulate flow at the micron scale in order to downsize standard experimental procedures. These techniques boast faster results while consuming less resources. Microfluidic devices can be used for point-of ... En savoir plus

A Dual Continuum Model for Groundwater Flow in Karst Aquifers

R. Painter[1], J. Harris[1], T. Byl[1], L. Sharpe[1]
[1]Tennessee State University, Nashville, TN, USA

In karst terrain, the interaction between the fast moving, highly turbulent conduit flow and the slow moving, laminar flow through porous media is largely unknown. Yet the dual nature of the karst system impacts the residence time of solutes in the groundwater supplies of over 25% of the ... En savoir plus

A Microfluidic System for Capturing Malaria-Infected Blood-Cells Using an Array of Nickel Structures

Pachara Noosawad [1],
[1] Chulalongkorn University, Thailand

Treatment and prevention of malaria, a disease having an anopheles mosquito as a carrier, have become a severe medical issue to many countries in a tropical zone. It was reported that there have been patients about 300-500 millions all over the world[1]. Many countries in South East Asia ... En savoir plus
