Finite Element Modeling of Freezing of Coffee Solution

C. Anandharamakrishnan, R. Gopirajah, and N. Chhanwal
Central Food Technological Research Institute
Mysore
Karnataka, India

Freeze-drying is a popular method of producing shelf stable particulate products and is of particular value for drying thermally sensitive materials (volatiles and biological based), which can be heat damaged by higher temperature methods, such as spray-drying. Porous structures are ... Read More

Surface Aeration System Modeling using COMSOL

G. Selembo, P. Selembo, J. Stanton, and G. Paulsen
University of North Carolina
Charlotte, NC

Surface aeration systems are used in the wastewater treatment industry for the transfer of oxygen in the activated sludge process. These systems are capital intensive and also require a significant amount of energy to operate. Scale-up and design of these systems is largely empirical, ... Read More

Modelling and Simulation of Simultaneous Intrinsic Kinetics, Hydrogen Transport and Heat Transfer in Complex Hydride Hydrogen Storage Systems

G. A. Lozano, J. M. Bellosta von Colbe, T. Klassen, and M. Dornheim
Institute of Materials Research
Materials Technology
Helmholzt-Zentrum Geesthacht
Geesthacht, Germany

In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, ... Read More

Modeling of Coupled Fluid Flow and Shear-induced Solidification Kinetics in Rheocasting of Aluminium Alloys

Politecnico di Torino
Dipartimento di Scienza dei Materiali ed Ingegneria Chimica
Torino, Italy

The model proposed by Schneider et al., for polymers is herein adapted in order to assess its suitability in elucidating the thixotropic behavior of aluminum alloys. The COMSOL Multiphysics program is employed to solve the inherent coupled mathematical problem, consisting in the ... Read More

Experimental and Numerical Study of Microbial Improved Oil Recovery in a Pore Scale Model by using COMSOL

M. Shabani Afrapoli, L. Shidong, S. Alipour , and O. Torsaeter
Department of Petroleum Engineering and Applied Geophysics
NTNU
Trondheim, Norway

A number of visualization experiments are carried out at the laboratory temperature with oil, brine and bacteria suspension for evaluating the performance of MIOR in a glass micromodel. The observations show the effects of bacteria on remaining oil saturation. The interfacial tension ... Read More

Mass Transfer From a Rotating Cylinder in a Confined Gas Flow

N. Jand[1], A. Scarpetta[2], and M. Stefano[2]
[1]Chemical Engineering Department, University of L’Aquila, L’Aquila, Italy
[2]Faculty of Engineering, University of L'Aquila, L’Aquila, Italy

The modeling of sublimation form a rotating cylinder of solid naphthalene in a confined vessel has been performed by coupling the model of incompressible Newtonian fluid flow with the model of the dilute solutions. Preliminary a 2D axisymmetric system with swirl flow function for laminar ... Read More

Modeling of Chemo-Mechanical Coupled Behavior of Cement Based Material

[3]Département de Chimie et de Biologie Appliquées, Institut National des Sciences Appliquées et de Technologie, B.P. N°676, 1080 Tunis Cedex, Tunis, Tunisie

The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... Read More

On the Drying Dynamics in Biofilters

F. Schönfeld
Hochschule RheinMain
University of Applied Sciences
Wiesbaden, Germany

The performance of biofilters relies on the presence of a sufficient amount of water in the biofilter material. And breakdown of filtration performance is often caused by inappropriate water content. The present study focuses on the drying dynamics within such filter, which are modelled ... Read More

Model of a Heavy Metal Adsorption System using the S-Layer of Bacillus Sphaericus

Dept. de Ingeniería Química Facultad de Ingeniería
Universidad de los Andes
Bogotá
Colombia

A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in detail ... Read More
