Simulation of a Diesel Oxidation Catalyst Used in a NO_x Storage and Reduction system for Heavy Duty Trucks

C. Odenbrand, and E. Senar Serra
Department of Chemical Engineering, Lund University, Lund, Sweden

This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic ... Mehr lesen

Analysis of Heat, Mass Transport, and Momentum Transport Effects in Complex Catalyst Shapes for Gas-Phase Heterogeneous Reactions Using COMSOL Multiphysics

[1]Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy
[2]Engineering Maintenance - ISAB Energy Services, Priolo Gargallo, Italy

In this study, COMSOL Multiphysics is applied in order to simulate reacting flows for duct burner systems arranged in the post-firing section of a Heat Recovery Steam Generator of a combined cycle power plant. Two- and three-dimensional simulations are carried out in order to ... Mehr lesen

Localization of Chemical Sources Using Stochastic Differential Equations in Realistic Environments

A. Mohammed, and A. Jeremic
McMaster University, Hamilton, L8S4K1, Canada

Signal processing algorithms for chemical sensing/monitoring have been subject of considerable research interest in the recent years mainly due to their diverse applicability. When the concentration of chemical agent is small, the dispersion of particles is governed by stochastic ... Mehr lesen

A Model of a Horizontal Atmospheric Pressure Chemical Vapor Deposition Reactor

T. Adams

Naval Surface Warfare Center Crane Division, CRANE, IN, USA

A model of a horizontal atmospheric pressure chemical vapor deposition reactor was implemented to aid in the design of a laboratory based one. The model coupled momentum transport, energy transport, and mass transport phenomena to account for reacting fluid flow of a compressible gas in ... Mehr lesen

Modeling and Simulation of Membrane Contactor Employed to Strip CO2 from Rich Solvents via COMSOL Multiphysics®

N. Ghasem[1], M. Al-Marzouqi[1], N. A. Rahim[1]
[1]United Arab Emirates University, Al-Ain, United Arab Emirates

A mathematical model is developed for the stripping of CO2 from rich solvent. The rich solvent (aqueous NaOH) is used in CO2 absorption from natural gas through gas-liquid hollow fiber membrane contactor. The polyvinylidene fluoride (PVDF) hollow fiber membrane was fabricated via ... Mehr lesen

Modeling an Adsorption Process in a Shell-and-Tube-Heat-Exchanger-Type Adsorber

G. Salazar Duarte[1], B. Schürer[1], C. Voss[1], D. Bathen[2]
[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

Virtual Pharmacokinetic Model of the Human Eye

L. Murtomäki[1], S. Kotha[2]
[1]Aalto University, Greater Helsinki, Finland
[2]University Of Helsinki, Helsinki, Finland

There is a great need for an effective drug treatment of the posterior eye, as the major reason for visual disability in industrial countries is Age-related Macular Degeneration (AMD). In USA alone, there are almost 2 million people affected by AMD [1]. A virtual pharmacokinetic 3D model ... Mehr lesen

[1]Universidade Nove de Julho - UNINOVE, São Paulo, SP, Brazil
[2]IPEN/CNEN-SP, São Paulo, SP, Brazil

This computational implementation presents a new strategy of coupling two 3D models to satisfy the requirements of the comprehensive model of a unitary Proton Exchange Membrane fuel cell, including its internal geometries and constitutive materials, as well as distinct physical and ... 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
