Modeling of a Biogas Steam Reforming Reactor for Solid Oxide Fuel Cell Systems

F. Cipitì[1]
[1]CNR-ITAE, Institute of Advanced Technologies for Energy, Messina, Italy

A biogas steam reforming reactor has been developed in order to be integrated into a proof-of-concept SOFC system, able to operate with biogas produced in an industrial waste water treatment unit. A mathematical model, aimed at describing the performance of the reactor, has been ... Per saperne di più

FSWR Microlith Performance Metrics Assessment

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

COMSOL Multiphysics® has been used to develop assessment tools for the NASA-sponsored Precision Combustion, Inc. (PCI) regenerable Microlith®- based adsorber modules. The Full Scale Water Removal (FSWR) PCI Microlith® was initially modeled for comparison with exit velocity data, ... Per saperne di più

Theoretical Study of Phase and Amplitude Characteristics of Microwave Coplanar Delay Line Containing Thin Ferroelectric Layer

[1]Saratov State University, Saratov, Russian Federation
[2]Joint International Laboratory LICS/LEMAC, IEMN UMR CNRS 8520, EC Lille, France

We theoretically studied the microwave coplanar line of different geometry based on MgO substrate with a thin (30 nm) ferroelectric layer under the external electric field using the environment of 3D modeling in COMSOL Multiphysics®, RF Module, Frequency Domain. Frequency dependence of ... Per saperne di più

Optimal Design of Flow Distributors for Detecting Blocked Microreactors

Osamu TONOMURA[1]
[1]Kyoto University, Kyoto, Kyoto, Japan

When the production capacity of micro chemical plants is increased by numbering-up approach, it is important to realize the uniform flow distribution among the parallelized microreactors. In addition, a blocked microreactor needs to be identified as early as possible to achieve the ... Per saperne di più

Analysis of Optical Manipulation of a Metallic Nanowire using COMSOL Multiphysics®

Ryota OZAWA et al.[1]

[1]Yokohama National University, Yokohama, Kanagawa, Japan

We have developed optically driven micropumps by manipulating microstructures using optical tweezers. In this study, we proposed and developed a novel manipulation method of a single metallic nanowire. In this method, dynamic optical vortex is used not only for manipulating a metallic ...

A Comparative Study of the Basic Flow Field Designs for High Temperature Proton Exchange Membrane Fuel Cells new

A. Lele[1], N. Lodha[1], R. Srivastava[1], A. Pandey[2], A. Paul[3]
[1]CSIR - National Chemical Laboratory, Pune, Maharashtra, India
[2]Reliance Industries Ltd., Reliance Technology Group, Navi Mumbai, Maharashtra, India
[3]CSIR - Central Electrochemical Research Institute, Karaikudi, Tamil Nadu, India

A Proton Exchange Membrane Fuel Cell (PEMFC) comprises a membrane-electrode assembly sandwiched between two conducting ‘monopolar’ plates having engraved gas flow channels, also called the flow field. The purpose of the flow field is to provide sufficient residence time for the gases to ... Per saperne di più

Analysis of Flow in a Microfluidic Device: Pressure Drop, RTD and Mixing

A. Kulkarni[1]
[1]NCL, Pune, Maharashtra, India

Continuous flow reactors are recently being used for lab scale synthesis as well as pilot scale manufacturing of high value low volume chemicals. Here we present our work on a new configuration of flow reactor that includes several 1800 bends and yet a varying radius of curvature thereby ... Per saperne di più

Permeability in Fragmented Materials and its Application to Underground Mining

S. Palma [1], R. Castro [1], A. Hekmat [1],
[1] Mining Engineering Department, Block Caving Laboratory, University of Chile, Santiago, Chile

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of ... Per saperne di più

Numerical Modeling of Solvent Enhanced Water Flooding

M. Chahardowli [1], R. Farajzadeh [2], H. Bruining [1],
[1] Delft University of Technology, Delft, The Netherlands
[2] Shell Global International Solutions, Den Haag, The Netherlands

Mutually soluble-solvents can improve the ultimate recovery in conventional reservoirs. Initially, the solvent moves with the imbibing aqueous phase into the reservoir. However, upon contact with oil, diffusion occurs and the solvent is transported in the oleic phase. Through the ... Per saperne di più
