Using Temperature Signals to Estimate Geometry Parameters in Fractured Geothermal Reservoirs

F. Maier[1], P. Oberdorfer[1], I. Kocabas[2], I. Ghergut[1], M. Sauter[1]
[1]Dpt. Applied Geology, Center of Geosciences, Georg-August-University, Göttingen, Germany
[2]Petroleum and Natural Gas Engineering Department Batman, Batman University, Batman, Turkey

We compare the output of 2D single fracture models as well as analytical solutions of the problem. The temperature signal is evaluated with the heat transfer mode while the flow field is assumed to exhibit Darcy flow everywhere. The problem is time-dependent so we have to take into ...

Heat and Mass Transfer in Reactive Multilayer Systems (RMS)

M. Rühl[1], G. Dietrich[2], E. Pflug[1], S. Braun[2], A. Leson[2]
[1]TU Dresden, Laser and Surface Technology, Dresden, Germany
[2]IWS Dresden, Fraunhofer Institute for Material and Beam Technology, Dresden, Germany

Established joining techniques like welding, soldering or brazing typically are characterized by a large amount of heat load of the components. Especially in the case of heat sensitive structures like MEMS this often results in stress induced deformation and degradation or even damaging ... En savoir plus

Comparison of Heat and Mass Transport at the Micro-Scale

E. Holzbecher[1], S. Oehlmann[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany

Phenomena of heat and mass transfer are often compared, in various porous media applications. Questions of practical interest are, for example, if tracers can be used for the prediction of heat flow, or vice versa if heat can be utilized as, possibly retarded, tracer for predicting the ...

Numerical Simulation of Recovery of Light Oil by Medium Temperature Oxidation in Porous Media

N. Khoshenvis Gargar[1], A. Mailybaev[2], D. Marchesin[2], H. Bruining[1]
[1]Delft University of Technology, Delft, The Netherlands
[2]Instituto Nacional de Matematica Pura e Aplicada, Rio de Janeiro, Brazil

One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. In this ... En savoir plus

Numerical and Experimental Investigation of Natural Convection Flow of (Sub-) and (Super-) Critical CO2 in Aqueous Phase

R. Khosrokhavar[1], G. Elsinga[1], R. Farajzadeh[2], H. Bruining[1]
[1]Delft University of Technology, Delft, The Netherland
[2]Shell International Global Solutions, Amsterdam, The Netherland

Optimal storage of carbon dioxide (CO2) in aquifers requires dissolution in the aqueous phase. Transfer of CO2 from the gas phase to the aqueous phase or oil phase would be slow if it were only driven by diffusion. Dissolution of CO2 in brine (oil) forms a mixture that is denser than the ...

Ammonia Removal From Water by a Liquid-Liquid Membrane Contactor Under a Closed Loop Regime

E. Licon[1], S. Casas[1], A. Alcaraz[1], J.L. Cortina[1], C. Valderrama[1]
[1]Universitat Politécnica de Catalunya, Barcelona, Spain

Ammonia separation from water by membrane contactor was simulated on transient state and compared with experimental data. Aqueous low concentrated solution of ammonium with high pH has been pumped inside the hydrophobic hollow fibers, acid solution in the outside part. The system is in ... En savoir plus

Numerical Simulations of Methane Aromatization with and without a Ceramic Hydrogen Separation Membrane

Z. Li[1], C. Kjølseth[2], S. Hernandez Morejudo[3], R. Haugsrud[1]
[1]University of Oslo, Department of Chemistry, FERMiO, Oslo, Norway
[2]Protia, Oslo, Norway
[3]University of Oslo, Department of Chemistry, InGAP, Oslo, Norway

Oxygen-free methane aromatization has been attracting growing attention due to a potential means for producing high valuable products such as aromatics and hydrogen. Many studies have been focused on catalysts screening and characterization, and elementary thermodynamic steps of the ... En savoir plus

Heat and Mass Transfer Modeling During Freezing of Foodstuffs

O. Rouaud[1], T. Pham[2]
[1]LUNAM Université, ONIRIS, CNRS, GEPEA, UMR, Nantes, France
[2]University of New South Wales, Sydney, Australia

A mathematical model is developed to determine the weight loss and the freezing rate during the freezing of unwrapped foodstuffs. The model allows comparing two freezing processes; the first uses nitrogen gas at -80°C and the second uses cold air. The model includes thermophysical ... En savoir plus
