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 ... Read More

Electromagnetic Wave Simulation in Fusion Plasmas

O. Meneghini[1], and S. Shiraiwa[1]
[1]Plasma Science and Fusion Center, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA

COMSOL has been used to model the propagation of electromagnetic waves in fusion plasmas. For the first time, a finite element method has been used to solve the wave propagation for realistic fusion plasma parameters in the lower hybrid and ion cyclotron frequency ranges. Moreover, for ... Read More

The Effect of Eccentricity in Fully Developed Annular Pipe Flow on Convection Heat Transfer and the Darcy Friction Factor

[1] Vaughn College of Aeronautics and Technology, New York, NY, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Eccentricity in annular channels contributes to changes in fluid flow characteristics which in turn, affects the performance and integrity of the configuration. This research investigates a model of an annular channel with a diameter ratio of 0.762, an aspect ratio of 68.9:1 and heating ... Read More

CFD Analysis of a Printed Circuit Heat Exchanger

K. Wegman [1], X. Sun [1],
[1] Department of Mechanical and Aerospace Engineering, Ohio State University, Columbus, OH, USA

In this experiment, the performance of a Printed Circuit Heat Exchanger (PCHE) was studied using COMSOL Multiphysics® software. PCHEs are diffusion bonded heat exchangers containing semicircular, chemically etched flow paths. Helium was used as the working fluid on both the hot and cold ... Read More

Urban Air Purification Using Semi-Active Photocatalysis

M. Boumahdi [1], J. Roegiers [2] , C. El Amrani [1] , S. Denys [2]
[1]Department of Computer Engineering, Abdelmalek Essaadi University, Tangier, Morocco
[2]Sustainable Energy, Air & Water Technology, Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

Photocatalysis has received considerable attention in recent years with a huge potential in air purification applications. This work focusses on the semi-passive use of photocatalytic surfaces in streets as an innovative method for removing anthropogenic pollutants (especially volatile ... Read More

Transient Model of a Fluorine Electrolysis Cell

J. Vukasin [1], I. Crassous [1], B. Morel [1], J. Sanchez-Marcano [2], P. Namy [3]
[1] HRP, AREVA NC, France
[2] Institut Européen des Membranes - CNRS, France
[3] Simtec, France

In the nuclear fuel cycle, fluorine is produced by the electrolysis of the molten salt KF-2HF. It is a complex process to study since hydrofluoric acid and fluorine are hazardous and highly corrosive. A 3D-model of a lab-scale fluorine electrolysis cell has been developed to increase ... Read More

A Dynamic Simulation of Heterogeneous Catalysis with COMSOL Multiphysics® software

A. K. Patan [1], M. Mekala [1], S. K. Thamida [1],
[1] National Institute of Technology, Warangal, Telengana, India.

Reaction-Diffusion equation is simulated for heterogeneous catalytic reaction involving a porous catalyst particle surrounded by liquid reactants. COMSOL Multiphysics® software along with transport of dilute species module is used for this purpose. Global Variables such as reaction ... Read More

Calculation of Cable Parameters for Different Cable Shapes

H. Lorenzen[1], J. Timmerberg[1], and S. Mylvaganam[2]
[1]Department of Electrical Engineering, UAS OOW, Wilhelmshaven, Germany
[2]Department Technology/Engineering, Telemark University College, Porsgrunn, Norway

Efforts involving simulation of transmission line networks necessitate the accurate values of the parameters of the lines. In this paper, as an attempt in estimating such parameters, the parameters of high voltage asymmetric power lines are calculated. In the process of estimation, the ... Read More

Ultrasound-assisted Microfluidic Devices: Insights and Optimization of Sono-microreactors

F. J. Navarro-Brull [1], P. Poveda [2], J. Ramis [2], R. Gómez [1],
[1] Departament de Química Física, Universidad de Alicante, Alicante, Spain
[2] Departament de Física, Enginyeria de Sistemes i Teoria del Senyal, Universidad de Alicante, Alicante, Spain

Possible drawbacks of microreactors are inefficient reactant mixing due to the predominance of laminar flow and clogging (when solid-forming reactions are performed or solid catalyst suspensions are used). Ultrasound has been successfully implemented not only to prevent these problems ... Read More

Hydrothemal Carbonization: A Renewable Alternative to Fossil Fuels and Respective Evaluation

P. Kladisios [1], A. Stegou [1], Z. Sagia [1],
[1] National Technical University of Athens, Athens, Greece.

Humanity is faced with an imminent energy crisis. The exponential growth of the human population and the consequential increase of the required energy on a global scale, the dramatic climate change and the exhaustibility of natural resources combined, force us to strive towards a ... Read More
