[1]Linde AG, Munich, Germany
[2]Universität Duisburg-Essen, Duisburg, Germany

Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA) are commonly used for separation/purification of gas mixtures in industrial processes. The cycle time of industrial TSA processes usually ranges from several hours to days. The reason for this long cycle time is the ... Mehr lesen

Analysis of Mash Tun Flow: Recommendations for Home Brewers

E. Gutierrez-Miravete[1], C. J. Walsh[2]
[1]Rensselaer at Hartford, Hartford, CT, USA
[2]General Dynamics-Electric Boat, Groton, CT, USA

The major steps in the beer making process are simple and with some skill, rather good brew can be produced using a common picnic cooler. First, grain (usually barley) is wetted and allowed to partially germinate before dried in a kiln (malting) Next, during mashing in a mash tun ... Mehr lesen

Paleohydrogeological Reactive Transport Model of the Olkiluoto Site (Finland)

M. Luna[1], P. Trinchero[1], J. Molinero[1], J. Löfman[2], P. Pitkanen[3], L. Koskinen[3]
[1]Amphos 21 Consulting, Barcelona, Spain
[2]VTT Energy, Espoo, Finland
[3]Posiva, Eurajoki, Finland

The safety assessment of the deep geological repository for nuclear waste of Olkiluoto (Finland) requires the evaluation of the influence of the land uplift (ice withdrawal) in groundwater. With this objective in mind, we have developed a three dimensional reactive transport model of ... Mehr lesen

Evolution of the Geochemical Background of an HLW Cell in the Callovo-Oxfordian Formation

O. Silva[1], M. Pekala[1], D. Garcia[1], J. Molinero[1], A. Nardi[1], M. Grive[1], B. Cochepin[2]

The French National Waste Management Agency (Andra) envisages the safe disposal of High-Level Waste Intermediate-Level Long-Lived Waste through deep geological storage (multibarrier). Waste storage is based on the Callovo-Oxfordian formation (CallOx). It has been updated a reactive ... Mehr lesen

A 2D Model of the Flow in Hydrocyclones

B. Chinè[1], F. Concha[2], M. Meneses G.[3]
[1]School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica
[2]Department of Metallurgical Engineering, University of Concepcion, Concepcion, Chile
[3]School of Production Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica

Hydrocyclones are industrial devices used as processing units in fluid and particle technology. A hydrocyclone is an apparatus consisting of a cylindrical or a cylindrical-conical body with a tangential or involute entrance to admit the fluid inside. There are also two opposite exits, ...

[3]Politecnico di Milano, Dipartimento di Meccanica, Milano, Italy

Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure represented by a metal or metal alloy and gas voids inside (Fig.1). A common metallic cellular material is aluminum foam which can be produced metallurgically by heating ... Mehr lesen

Void Shape Evolution of Silicon: Level-Set Approach

C. Grau Turuelo[1], C. Breitkopf[1]
[1]Technische Universität Dresden, Dresden, Germany

The void shape evolution of silicon is a process driven mainly by surface diffusion which leads to a geometrical transformation of trenches etched in silicon wafers due to surface energy minimization. The temperature, the ambient gas and the annealing time affect the velocity of the ... Mehr lesen

Optimization of Jet Mixer Geometry and Mixing Studies

A. Egedy[1], B. Molnar[1], T. Varga[1], T. Chován[1]
[1]Department of Process Engineering, University of Pannonia, Veszprém, Hungary

The primary aim of using jet as mixer, like in case of other mixing devices, is to increase the heat and mass transfer between the phases. Beside the injection position the geometry of the jet mixer and the injection nozzle has a major effect on the injection. In our study COMSOL ... Mehr lesen

Modeling of Kinetic Interface Sensitive Tracers for Two Phase Immiscible Flow in Porous Media with COMSOL Multiphysics® Software

A.-B. Tatomir[1], F. Maier[1], A. Jyoti[1], M. Sauter[1]
[1]Geoscience Centre of the University of Göttingen, Göttingen, Germany

The understanding of the tracer migration in two-phase porous media systems and its reaction over the fluid-fluid interfaces is a challenging task important for a number of engineering applications, e.g. oil recovery, carbon capture and storage in geological reservoirs, remediation ... Mehr lesen

Numerical Analysis of Mass Transfer Rate in Droplet Flow at Microscopic Scales

S. Cito[1], T. Sikanen[1]
[1]Division of Pharmaceutical Chemistry and Technology, Faculty of Pharmacy, University of Helsinki, Helsinki, Finland

Droplet flow at microscopic scale is often used to enhance many pharmaceuticals and industrial processes (i.e. liquid–liquid micro-extraction, nanoparticle synthesis, slow reactions in microfluidic devices, etc.). In all these processes, the mass transfer rate, at the interface between ... Mehr lesen
