CFD Simulations to Improve Protein Separation Introducing a Permeable Surface with Periodic Grooves

M. Marioli [1], W. Th. Kok [1],
[1] Analytical Chemistry Group, van’t Hoff Institute for Molecular Sciences, University of Amsterdam, The Netherlands

In this study, we use COMSOL Multiphysics® to improve protein separations by the analytical technique asymmetrical flow field-flow fractionation (AF4). AF4 is a very mild separation technique where separation of macromolecules or nanoparticles takes place along a ribbon-like channel that ... Mehr lesen

iCP Apps to Readily Solve Reactive Transport Simulations in COMSOL Multiphysics®

D. Negro [1], A. Sainz-Garcia [2], D. Sampietro [1], E. Coene [1], E. Abarca [1], A. Idiart [1], M. Laviña [1], O. Silva [1], J. Molinero [1],

Reactive transport models (RTM) that couple physical and chemical processes are commonly used to solve a large variety of problems in the environmental industry. There are a series of codes designed to solve this kind of problems. However, their use requires typically much effort due to ... Mehr lesen

Modeling and Simulation of Redox Titration of Metal Oxides at Porous Microelectrodes

L. Balboa [1], M. Hänsch [1] , J. Behnken [1], G. Wittstock [1],
[1] Institute of Chemistry, Carl von Ossietzky University of Oldenburg, Oldenburg, Germany

In the past two decades, highly porous nanostructured materials have been investigated and used for a large variety of applications, such as catalysis, energy conversion/storage, optics, sensing and more. Nanoporous gold (npAu) is one of such materials which have shown great potential as ... Mehr lesen

Sterilization is the process of deactivating microorganisms from a surface or a product. A high temperature gaseous mixture of hydrogen peroxide and steam became the accepted standard in most aseptic filling machines found in pharmaceutical, food and beverage industries [1, 2]. To ... Mehr lesen

Modeling and Simulation of Hydrogen Generation in Membrane Reactor via Steam Octane Reforming

N. Ghasem [1], A. Y. Alraeesi [1],
[1] UAE Univeristy, Alain, United Arab Emirates

Various hydrocarbon compounds have been converted into pure hydrogen by using a catalyst and a palladium membrane in one reactor (PMR) in a one-step process where the reaction proceeds to almost complete conversion. Octane is converted into pure hydrogen using of a palladium membrane ... Mehr lesen

Simulation and Visualisation of Shielding Gas Flows During Wire-Arc Additive Manufacture

I. Bitharas [1], A. Moore [1],
[1] Heriot-Watt Univerisity, Edinburgh, UK

One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... Mehr lesen

Non-linear DC Electrophoresis in High Electric Field Conditions

E. Ruiz-Reina [1], F. Carrique [1],
[1] University of Málaga, Málaga, Spain

Very recently, the synthesis and experimental study of a new class of highly charged polymer particles has been described, which spontaneously charge in non-aqueous low-polarity solvents [1,2]. These suspensions are an example of what is known as salt-free systems. The study of ... Mehr lesen

A Flow and Transport Model for Low-Temperature Gaseous Nitrocarburizing of Stainless Steels

J. Feng [1], M. Wettlaufer [1],
[1] Centre of Materials Engineering, Heilbronn University, Heilbronn, Germany

An integrated numeric, thermodynamic, and experimental analysis work was conducted to find out the proper flow and transport parameters of combined chemical species for low-temperature gaseous nitrocarburizing of stainless steels in an industrial furnace built for thermochemical ... Mehr lesen
