Crust which develops at the surface of meat leads to reactions which affect food color, flavor and safety. Whole pieces of meat are only contaminated by microorganisms at their surface. Thus intense thermal treatment can inactivate pathogenic bacteria; however the associated high temperatures also lead to the formation of carcinogenic compounds. An experimental study of crust development at ...

Analysis of Deformation of a Liquid Packaging Made With Board of the LPB Type

K. B. Matos [1], I. Neitzel [1],
[1] FATEB, Telêmaco Borba, PR, Brazil

The liquid food product packaging are today predominantly made with board LPB type board (Liquid Packaging Board) composite formed by board, which offers mechanical strength, polyethylene, constituent responsible for protection against the passage humidity, and aluminum foil, which helps protect against oxygen flow. On the day, paper and board are words used as synonyms for each other. ...

Simulation of a Diesel Oxidation Catalyst Used in a NOx 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 oxidation catalyst mounted after a heavy duty diesel engine in a rig. The conversion of hydrocarbons is ...

Validation of Supercritical Fluid Extraction Model with COMSOL Multiphysics® Software

V. Devi [1], R. Bhargava [1], S. Khanam [1],
[1] Indian Institute of Technology Roorkee, Uttarakhand, India.

This paper shows the solution of mathematical model of supercritical fluid extraction process, given by Sovova H., 1994, through COMSOL Multiphysics® software. Sovova et al., 1994 used this model for the supercritical CO2 extraction of grape seed. Extraction was performed with different specific flow rates and grade of grinding. Further Mira et al., 1996 and Mira et al., 1999 validated the same ...

Modeling an Enzyme Based Electrochemical Blood Glucose Sensor with COMSOL Multiphysics

S. Mackintosh[1], J. Rodgers[1], S.P. Blythe[1]
[1]Lifescan Scotland, Inverness, Scotland

This paper describes the modeling of a blood glucose sensor using COMSOL Multiphysics. Chemical species interaction and diffusion, coupled with electrochemical oxidation of multiple blood species produced a powerful working model used in developing and refining a range of blood glucose sensors for the commercial market.

Reactive Transport and Convective Mixing During CO2 Migration in a Saline Aquifer

E. Abarca[1], A. Nardi[1], F. Grandia[1], J. Molinero[1]
[1]Amphos21 Consulting, Barcelona, Spain

The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. A configuration of denser CO2-enriched brine overlying lighter water leads to convective flow and the formation of gravity fingers ...

Transport-Kinetic Interactions for SO2 Oxidation to SO3 in Particulate and Monolith Catalysts - new

Introduction: After more than 20 years of experience in EV applications, the sodium nickel chloride technology is fully mature for large scale energy storage. Early on, mathematical modeling of Na-MCl2 cell (M standing for Fe or Ni) has attracted attention to help identifying predominant mechanisms at work during operation. However, these models were rarely validated with data coming from ...

Numerical Analysis of the Self-Heating Behaviour of Coal Dust Accumulations - new

D.Wu[1], E. Van den Bulck[1]
[1]Katholieke Universiteit Leuven, Department of Mechanical Engineering, KU Leuven, Belgium

Introduction Self-heating behaviour of dust accumulations is a multiphysics field coupled heat and mass transfer in the porous media. A typical experimental apparatus with a hot storage oven and mesh wire baskets has been taken as the study object. The influence of gas flow velocity, oxygen concentration and ambient temperature on the self-heating behaviour of the dry coal dust sample has been ...

Multi-Dimensional Adsorption Model of CO2/H2O Sorbent Bed
