Modeling of Turbulent Combustion in COMSOL Multiphysics®

D. Lahaye[1], L. Cheng[2]
[1]DIAM, EEMCS Faculty, TU Delft, The Netherlands
[2]Tsinghua University, Beijing, China

In the production of high quality materials by a heat treatment, it is indispensable to accurately predict the temperature inside the furnaces being employed. In this work we develop a turbulent combustion model for the heat being released by gas burners inside a shaft kiln. Turbulent ... En savoir plus

FEM Based Studies of a Mg/Al Hybrid Component Joint Regarding Corrosion Prediction

D. Höche[1]
[1]Helmholtz-Zentrum Geesthacht, Germany

The model can be utilized for a virtual design of a hybrid joint interms of corrosion prevention. Structures can be optimized by the simulations by tailoring the parameters to get the most suitable result towards a Computer-Aided Engineering CAE regarding corrosion protection. This kind ...

Developments in a Coupled Thermal-Hydraulic-Chemical-Geomechanical Model for Soil and Concrete

S.C. Seetharam[1], D. Jacques[1]
[1]Performance Assessments Unit, Institute for Environment, Health and Safety, Belgian Nuclear Research Centre (SCK•CEN), Mol, Belgium

This paper documents current status in the development of a coupled thermal-hydraulic-chemical-geomechanical numerical suite within COMSOL-MATLAB environment to address soil and concrete applications. The mathematical formulations are based on well-established continuum scale models ... En savoir plus

Combustion Study of DDGS Char from Steam-O2 Blown CFB Gasifier and Charcoal Using Thermogravimetric Analysis and COMSOL Multiphysics®

X. Meng[1], W. de Jong[1], A.H.M. Verkooijjen[1]
[1]TU Delft, Delft, The Netherlands

To obtain reliable kinetic data for the modeling of Dried Distiller’s grains with Soluble (DDGS) gasification using a 100 kWth steam-O2 blown circulating fluidized bed (CFB) gasifier, the combustion behavior of partially gasified residual DDGS char and pure charcoal as a comparison has ...

Can Oscillatory Convection Accelerate Signal Propagation in Simple Epithelium?

M. Nebyla[1], M. Pribyl[1]
[1]Institute of Chemical Technology, Prague, Department of Chemical Engineering, Prague, Czech Republic

We introduce a mathematical model of signal transmission in simple epithelial layers. The mathematical model consists of reaction-transport equations for extracellular ligands, cellular receptors, ligand-receptor complexes and a ligand releasing protease. We consider diffusion and ...

Chromatographic Separation of Tröger’s Base in a Batch Column

A. Fayolas [1], M.G. Sanku[1], M. Pascoa[1], M. Xynou[1]
[1]KTH Royal Institute of Technology, Stockholm, Sweden

The objective of the study is to investigate the chiral separation of Tröger’s base enantiomers using batch chromatography. Because of its resolution, chromatography is often the preferred method for chiral separations. The separation of Tröger’s base is resolved by using the COMSOL ... En savoir plus

Reactive Transport and Convective Mixing During CO2 Migration in a Saline Aquifer

E. Abarca[1], A. Nardi[1], F. Grandia[1], J. Molinero[1]
[1]Amphos21 Consulting, Barcelona, Spain

The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. A configuration of ... En savoir plus

Turbulent Premixed Combustion with FGM in COMSOL Multiphysics®

R. Bastiaans[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

In this paper a new method for turbulent combustion modeling is introduced in COMSOL Multiphysics®. The method is called Flamelet Generated Manifolds (FGM). The method is based on the concept of flamelets, elemental reaction layers in combustion. The only hypothesis is that the turbulent ... En savoir plus

[1]BAM Federal Institute for Materials Research and Testing, Berlin, Germany
[2]Chairman PlasticsEurope Fluoropolymers TFE Safety Task Force, Du Pont De Nemours, Dordrecht, The Netherlands

The self-ignition of tetrafluoroethylene (TFE) caused by contact with hot surfaces has been analyzed with the help of simulations performed with COMSOL Multiphysics®. The current study focuses on large-scale heated reactors for the industrial production of polytetrafluoroethylene (PTFE) ... En savoir plus

Modeling the Vanadium Oxygen Fuel Cell

F.T. Wandschneider[1], M. Küttinger[1], P. Fischer[1], K. Pinkwart[1], J. Tübke[1], H. Nirschl[2]
[1]Fraunhofer-Institute for Chemical Technology, Pfinztal, Germany
