Modeling Scheil Cooling of a Metal Alloy: Thermodynamic and Multiphysics Solidification

T. Marin-Alvarado [1],
[1] M4Dynamics, Toronto, ON, Canada

During solidification of a multicomponent liquid, either a metal alloy, a sulphide matte or an oxide slag system, the process is highly dependant not only on temperature but in composition as well. The thermodynamic properties of the system will dictate what phases or mixtures ... En savoir plus

A COMSOL Multiphysics® Software Interface with GEMS3K for Modeling Reactive Transport (Geo)Chemical Processes

O. B. Isgor [1], V. J. Azad [1],
[1] Oregon State University, Corvallis, OR, USA

This paper presents a generic interface for reactive transport process modeling that was developed between the COMSOL Multiphysics® software Java API (transport model) and GEMS3K (reaction model). While the transport of different species, kinetics of dissolution/precipitation, system ... En savoir plus

On the Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption

J. Knox [1],
[1] Marshall Space Flight Center - NASA, Huntsville, AL, USA

This work examined in detail the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer information from experimental breakthrough data and the consequences that may arise when doing so based on using a 1-D axially ...

Numerical Simulation of Kinetic Interface Sensitive Tracer in Experiment with COMSOL Multiphysics® Software

F. Sun [1], A. Tatomir [1], F. Maier [2], M. Sauter [1]
[1] University of Goettingen, Goettingen, Lower Saxony, Germany
[2] Comsol Multiphysics GmbH, Goettingen, Lower Saxony, Germany

The kinetic interface-sensitive tracers (KIS tracers) are used to give a partial picture of the spreading, mixing and plume migration of supercritical carbon dioxide (scCO2) in the deep saline aquifer by estimating the interfacial areas between scCO2 and brine during the injection of ...

Efficiently Solving the Stochastic Reaction-Diffusion Master Equation in C++ with the COMSOL Multiphysics® Software

L. A. Widmer [1], J. Stelling [1],
[1] Department of Biosystems Science and Engineering, ETH Zürich and Swiss Institute of Bioinformatics, Basel, Switzerland

We demonstrate a simulation engine using COMSOL® and MATLAB® software that is able to simulate stochastic reaction-diffusion models in the reaction-diffusion master equation framework. We use this engine to construct models of budding yeast cells with embedded microtubules, interfacing ... En savoir plus

Optimization of Product from a Segregated Reactor via a Hybrid Modeling Approach

Clariant Produkte (Deutschland) GmbH, Burgkirchen, Germany

In the field of chemical reaction engineering chemical kinetics and fluid dynamics are described by various mathematical approaches. Such tools help to shorten the time-to-market of novel products and processes. Thanks to the continuously improving computation power, it is possible to ... En savoir plus

Molecular Hydrogen Tracking in an Electrolytic Polishing Process

L. M. A. Ferreira [1],
[1] CERN, Geneva, Switzerland

In a water based electrolytic polishing process, the formation of molecular hydrogen at the cathode is unavoidable and it can contribute to the formation of surface defects at the anode side. This paper presents the work to model and simulate the molecular hydrogen flow inside radio ... En savoir plus

The Simulation of Flow and Reduction of NO in a Heterogeneous Reactor.

O. Śliczniuk [1], B. Olejnik [1],
[1] Wrocław University of Technology, Faculty of Chemistry, Department of Chemical Engineering, Wrocław, Poland

Nitrogen oxides are one of the more dangerous ingredients contaminating the atmosphere. They are considered to be almost ten times more harmful than carbon monoxide, and sulfur dioxide several times. A whole range of photochemical reactions involving nitrogen oxides are responsible for ... En savoir plus

Column Adsorption of Copper and Silver Ions on Modified Porous Glass

M. Witczak [1],
[1] Wroclaw University of Technology, Wroclaw, Poland

Constantly growing industry necessitates the development of more effective methods to protect the environment against waste in the form of metal ions. Among many methods used to purify the environment from damaging substances a very attractive and efficient method is adsorption. In this ... En savoir plus

Modeling and Simulation of Flat Sheet Membrane with Physical and Chemical Absorption

N. Ghasem [1], M. Al-Marzouqi [2],
[1] UAE University, Al-Ain, UAE
[2] UAE University, Al-Ain, UAE

Greenhouse gases trap heat and make the planet warmer. The main greenhouse gases emitted by human activities are: Carbon dioxide (CO2). The use of fossil fuel is the primary source of CO2 [1, 2]. Accordingly, there is a need for an efficient and novel separation processes for removal of ... En savoir plus
