Modeling of Iron Ore Reduction Above the Cohesive Zone of the Blast Furnace

Yalçın Kaymak1, Hauke Bartusch1, Thorsten Hauck1
1VDEh Betriebsforschungsinstitut GmbH, Düsseldorf, NRW, Germany

The blast furnace shaft is a huge counter flow reactor in which heat and mass exchange play a significant role in its mathematical modelling. The heat exchange model is already available in COMSOL Multiphysics® via the Local Thermal Non-Equilibrium interface. This multiphysics coupling ... 詳細を見る

Modeling of Delayed Desorption in Activated Carbon Filter Systems for Air Purification Applications.

K. Schoofs1
1UAntwerpen

Activated carbon filtration has proven to be a reliable method to clean indoor air. In such a system, air, contaminated with VOCs, is led through the filter where the contaminants are adsorbed onto the filter. However, for the long term stability of the air purification system, it is ... 詳細を見る

Influence of the Complexing Agent on the Throwing Power during Silver Electroplating

C. Baumer1, A. Bund1
1Technische Universität Ilmenau, Ilmenau, Germany

The throwing power is an important criterion for the industrial use of an electrolyte in electroplating applications. Using the Electrodeposition Module and COMSOL Multiphyiscs® it is possible to simulate the thickness distribution for various electroplating geometries. For a realistic ... 詳細を見る

A COMSOL Multiphysics® 3D CFD Model for Describing the Gas Exchange Through Microperforations

Sara Vega-Diez1, María L. Salvador2, Jaime González-Buesa1

2Grupo de Investigación en Alimentos de Origen Vegetal, Instituto Agroalimentario de Aragón-IA2 (Universidad de Zaragoza-CITA), Spain

Modified Atmosphere Packaging (MAP) is a widely applied technology for the shelf-life extension of fresh and fresh-cut fruits and vegetables. This technique relies on modifying the gas composition inside de package by the respiratory activity of the product and the gas exchange through ... 詳細を見る

Reinforcement Bars Corrosion in a Carbonated Concrete

Bruno Chiné1, Ronald Jiménez Salas1, Rommel Cuevas Kauffmann2
1School of Materials Science and Engineering, Costa Rica Institute of Technology Cartago, Costa Rica
2School of Construction Engineering, Costa Rica Institute of Technology Cartago, Costa Rica

In the construction sector, the concrete and the steel bars represent still the key components, although they are very vulnerable by the atmospheric agents, as in the case of their degradation caused by corrosion. The value of the concrete carbonation may enhance the corrosion around the ... 詳細を見る

COMSOL Multiphysics® Model of an Industrial Top-Fired Steam Methane Reforming Reactor

Paola Costamagna1, Valeria Tacchino1, Silvia Rosellini2, Valter Mantelli2, Alberto Servida1
1DCCI, Department of Chemistry and Industrial Chemistry, University of Genoa, Via Dodecaneso 31, 16146 Genoa, Italy
2Iplom S.p.A., Via Navone 3b, 16012 Busalla (GE), Italy

Figure 1 shows a simplified scheme of a typical industrial steam methane reforming (SMR) reactor, which is a top-fired, packed-bed multi-tubular chemical reactor, consisting of a series of catalytic tubes arranged within a furnace. The tubes contain two adjacent catalytic sections filled ... 詳細を見る

In-Situ Scale Inhibitor Interaction with Surface Area of Porous Sandpack: A Numerical Approach.

Uche C. Anyanwu1
1Department of Engineering, Robert Gordon University, Aberdeen, AB10 7GJ, Scotland, UK

ABSTRACT: Over the years, the most common method of preventing scale formation and blockage of formation pores in oil and gas systems is by squeezing of chemicals into the formation. Different experimental and simulation studies have been carried out to understand the interaction of the ... 詳細を見る

CFD modeling of a commercial CVD system and simulation of a CVD deposition process

Oscar Alm1, Micael Baudin1
1Seco Tools, Sweden

Seco Tools produces inserts for machining metals. Roughly half the number of inserts Seco Tools produces are coated by Chemical Vapour Deposition (CVD) which extends the inserts lifetime in machining operations significantly. More than 10 000 inserts are coated on trays in each CVD run. ... 詳細を見る

V. Cabrera1, Á. Yustres1, R. López-Vizcaíno1, V. Navarro1
1Geoenvironmental Group, Civil Engineering School, University of Castilla-La Mancha, Avda. Camilo José Cela s/n, 13071 Ciudad Real, Spain

The study of the movement of solutes and their interaction with the solid phase of active clays is a problem of maximum interest in various geoenvironmental engineering applications, but especially in the deep geological disposal of spent nuclear fuel and other highly radioactive ... 詳細を見る

Modeling of an industrial scale packed bed reactor for steam reforming applications.

A. Biasin1, M. Guiotto1
1CASALE SA, Lugano, Switzerland

In this work, the modeling of an industrial scale, single tube, packed bed reactor for steam reforming (SR) application, typically used to provide hydrogen for ammonia synthesis, is discussed. The tightly coupled mass, energy, and momentum equations used to describe the system have been ... 詳細を見る
