Development of an On-Line Wall-Fouling Sensor for Pipeline Transportation of Heavy Oil-Water Mixtures

S. Rushd[1], and R.S. Sanders[1]
[1]Chemical & Materials Engineering Department, University of Alberta, Edmonton, AB, Canada

A beneficial method for transporting highly viscous hydrocarbons (e.g. heavy oil and bitumen) through a pipeline is known as Lubricated Pipe Flow (LPF). A major challenge for this technology is flow instability caused by the formation of a wall-coating of oil or the thinning and/or loss ... En savoir plus

Predicting the Fate of Contaminant and Remediating Nano-Particles in a Polluted Aquifer with an Integrated Modeling Approach

S. Nilabh[1], F. Grandia[1]
[1]Amphos 21 Consulting S.L., Spain

The presence of anthropogenic or natural pollutants in groundwater system poses a threat to water resources. Several remediation techniques have been explored and developed to decrease the concentration of contaminants. One such remediation technique, injection of nano-particles in the ... En savoir plus

Powder consideration for additive manufacturing simulation

¹Laboratoire Procédés et Ingénierie en Mécanique et Matériaux (PIMM) – UMR 8006, Arts et Metiers Institute of Technology, CNRS, CNAM, PIMM, HESAM Université, F-75013 Paris, France
²Arts et Metiers Institute of Technology, University of Bordeaux, CNRS, Bordeaux INP, INRAE, I2M Bordeaux, Talence F-33400, France

As additive manufacturing for metallic material is more and more used in industry, researchers try to overcome the limits of the process. To improve this industrial process, in terms of applications and understanding, the numerical simulation is today a very strong tool. Nevertheless, ... En savoir plus

Simulation of Mass Transfer in a Microfluidic Experiment Using the Moving Mesh Method

K. Weisbrod[1], R. Roberts[1], R. Chamberlin[1], S. Yarbro[1]
[1]Los Alamos National Lab, Los Alamos, NM, USA

Multiphase flow in a microreactor was studied numerically for two immiscible liquids. Validation of the model was sought by simulating the flow behavior and mass transfer characteristics of a neutralization reaction described in the literature. Contact angles, interfacial tension and the ... En savoir plus

Conjugate Heat Transfer

J. Crompton[1], L. Gritter[1], S. Yushanov[1], K. Koppenhoefer[1]
[1]AltaSim Technologies, Columbus, OH, USA

Quenching from high temperature by fluid flow has been analyzed; when no phase transformation occurs heat transfer is a function of conduction and convection. Flow conditions may lead to turbulent flow that affects the heat dissipation over the surface. Analysis of heat transfer with ... 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

Design and Simulation of High-Throughput Microfluidic Droplet Dispenser for Lab-on-a-Chip Applications

Supercritical CO₂ Leakage Modelling for Well Integrity in Geological Storage Project

E. Houdu, O. Poupard, and V. Meyer
OXAND S.A., France

CO2 capture and storage constitutes a promising solution to control and reduce these emissions. Wellbore integrity is a key challenge to ensure long term safety and for public acceptance. For this objective, a two-phase flow model in porous media based on Darcy’s law has been proposed to ... En savoir plus

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

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 ... En savoir plus
