She is a senior research engineer at NASA Glenn Research Center and specializes in the formulation and solution of problems in microgravity science, multiphase flow, porous media, risk ... Read More

Efficient Heat Management Technique for Electronic Display Device

U. Shukla[1], and D. Gupta[1]
[1] Department of Materials and Metallurgical Engineering, Indian Institute of Technology Kanpur, Uttar Pradesh, India

One of the major challenges faced by the semiconductor industry is that electronic circuits produce a lot of heat energy during their operation. And with the current scenario where the gates are packed so much close together, then the problem of heat generation has become extremely ... Read More

Porous Media Based Model for Deep-Fat Vacuum Frying Potato Chips

A. Warning, A. K. Datta, A. Dhall, and D. Mitrea
Department of Biological and Environmental Engineering
Cornell University
Ithaca, NY

A multiphase porous media model involving heat and mass transfer within a potato chip was implemented in COMSOL 3.5a. The diffusive flux in oil and liquid water was modeled from capillary driven flow while the gas phase was modeled using binary diffusion. A non-equilibrium water ... Read More

Flow Induced Oscillations of Marine Risers with Wake Interference

F. Van den Abeele, and J. Vande Voorde
OCAS N.V., J.F. Kennedylaan 3, Zelzate, Belgium

With offshore oil and gas exploration and production moving into ever deeper waters, the suspended length of marine risers (transporting hydrocarbons from the seabed to the surface) can easily exceed 3000 meters. One of the major design requirements for risers in (ultra) deep water is to ... Read More

Boundary conditions in multiphase, porous media, transport models of thermal processes with rapid evaporation

A. Datta[1], and A. Halder[1]
[1]Biological and Environmental Engineering, Cornell University, Ithaca, New York, USA

In modeling of thermal processing of biological materials with rapid evaporation, it is critical to provide boundary conditions consistent with the phenomena happening at the surface to accurately predict spatial temperature and moisture content for quality and safety assurance. Boundary ... Read More

Design and Simulation of an Electromagnetic Valve Actuator Using COMSOL Multiphysics

R. Wislati , H. Haase
Leibniz Universität Hannover, Germany

In this paper an electromagnetic solenoid actuator (EMVA) consisting of an upper and lower electromagnet, a linear moving armature and two preloaded springs is considered as a potential approach in Variable Valve Actuation (VVA) Systems for Internal Combustion Engines. In opposition to ... Read More

Droplet Generation by Means of a Two-Fluid Probe

B.P. Cahill[1], M. Quade[1], G. Gastrock[1], K. Lemke[1], J. Metze[1], and D. Beckmann[1]

[1]Institut für Bioprozess und Analysenmesstechnik e.V., Rosenhof, Heilbad Heiligenstadt, Germany

This paper presents a simulation of the operation of a new type of droplet generation probe. This probe, consisting of two concentrically-arranged tubings, is immersed in a beaker of cell medium so that oil is pumped through the outer tubing at a pumping speed less than fluid is drawn ...

CFD Simulation of Pore Pressure Oscillation Method to Measure the Permeability of Tight Formations

M. Mokhtari [1], S. A. Madani [1], A. Seibi [1],
[1] Department of Petroleum Engineering, University of Louisiana at Lafayette, Lafayette, LA, USA

Accurate estimation of rock permeability and porosity play a crucial role in the evaluation of oil and gas reservoirs. This evaluation is, however, challenging in tight formations such as shale due to the slow transition of fluid in such formations with extremely-low permeability. To ... Read More

Poromechanics Investigation at Pore-scale Using Digital Rock Physics Laboratory

S. Zhang[1],
N. Saxena[2],
P. Barthelemy[1], and
M. Marsh[1]
[1]Visualization Sciences Group, Burlington, MA, USA
[2]Stanford University, Palo Alto, CA, USA

Understanding the rock structure at nano to micro scale is of growing importance in geology, oil and gas, and hydrology. New approaches that relies on a variety of high resolution 3D imaging techniques offered tremendous potential. These new approaches, in the meanwhile, introduce ... Read More
