Numerical Simulation of Flow and Heat Transfer of a Ferrofluid in a Partially Filled Porous Channel in a Gradient Magnetic Field

Furlani E.P., Jafari A., Mokhtare A., University at Buffalo, US

Unique interactions of ferrofluids with magnetic fields can be exploited to achieve enhanced heat transfer for myriad fluidic based applications. In this study, we use a numerical simulation to investigate the transient behaviour of flow [...]

Nanoscale Flow Chip Platform For Laboratory Evaluation Of Enhanced Oil Recovery Materials

Bryant P.W., Engel M., Giro R., Neumann R.F., Steiner M.B., IBM Research Brazil, BR

We present a lab-on-chip platform for the experimental evaluation of Enhanced Oil Recovery [EOR] methods from the nanoscale to the scale of reservoir rock pore networks. We have employed semiconductor process technology to build lab-on-chip [...]

Rheological Behavior of Novel Switchable Cationic Surfactant in High Salinity Carbonate Reservoirs

Gurusinghe N., Liebum M., Nguyen Q.P., Ramadan G., The University of Texas at Austin, US

The use of viscoelastic (VES) or polymer-like surfactant solutions are important in applications related to enhanced oil recovery and subsurface conformance control. VES resembles polymer where it acts as a mobility control agent to promote [...]

Mobility of paramagnetic nanoparticles in porous media

Abriola LM., Bagaria H., Johnson K., Pennell KD., Wang Y., Zhang X., Tufts University, US

Stable paramagnetic nanoparticles were prepared and their mobility in reservoir matrix was measured as a function of particle mass loading, rate of sulfonate fraction in coating polymer, and the presence of surfactant.

Modeling of gas dynamic behaviour of CCSO in nanostructured media

Filimonov I.A., Markov A.A., Martirosyan K.S., University of Texas at Brownsville, US

Recently a novel, simple and energy efficient synthesis of nanoparticles of complex oxides referred to as Carbon Combustion Synthesis of Oxides, (CCSO) was developed. In CCSO the exothermic oxidation of nanoscale carbon generates a thermal [...]

A Novel Approach for Modeling Mechanical Behavior of Porous Media

Altan B.S., Mollamahmutoglu M., Bayburt University, TR

A multi-scale novel homogenization technique is introduced to model mechanical behavior of open-cell porous media. The proposed method has primarily three components. The first component is based on two assumptions. First, a random porous structure [...]

The Model of Porous Media – Complete Description for Aggregation of Bead-Monolayers in Flat Microfluidic Chambers

Brenner T., Dobmeier M., Ducrée J., Grumann M., Schippers P., Zengerle R., IMTEK, University of Freiburg, DE

In this paper we for the first time adopt the model of porous media to simulate the complete course of the formation of monolayers from bead suspensions in a flat microfluidic chamber. The chambers are [...]

Analysis of AC-Driven Electroosmotic Flow in a Microchannel Packed with Microspheres

Huang X.Y., Kang Y.J., Yang C., Nanyang Technological University, SG

This paper presents a theoretical study on the AC-driven electroosmotic flow in both open and closed cylindrical microchannels packed with uniform microspheres. The time-periodic oscillating electroosmotic flow in an open microchannel in response to the [...]

Modeling the Microstructure and Elastic Properties of Complex Materials

Garboczi E.J., Roberts A.P., University of Queensland, AU

The finite element method is used to study the influence of porosity and pore shape on the elastic properties of model porous media. The Young's modulus of each model was found to be practically independent [...]
