Modeling Maillard Reaction and Thermal Transformations During Bread Baking

D. Papasidero[1], F. Manenti[1]
[1]Politecnico di Milano, Dipartimento di Chimica, Materiali e Ingegneria Chimica “Giulio Natta”, Milano, Italy

One big challenge for the food industry is to predict and optimize flavors. The Maillard reaction occurs in food matrices containing carbohydrates and proteins under specific operating conditions. The presented research couples thermal and kinetic modeling to the bread baking process, ... Read More

Optimized Channel Geometry of a Flow-Focusing Droplet Generator for Parallelization

D. Conchouso[1], E. Al Rawashdeh[1], D. Castro[1], A. Arevalo[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

This document presents the Computational Fluid Dynamics (CFD) simulation of a commonly used Microfluidic Droplet Generator (MFDG) using the Laminar Two-Phase Flow, Phase Field method in COMSOL Multiphysics®. The paper discusses the effect of the channel’s geometry in droplet size at ... Read More

Modeling Plant Morphodynamics in Predefined COMSOL Multiphysics® Interface

S. Nikolaev[1], A. Trubuil[2]
[1]Institute of cytology and genetics SB RAS, Novosibirsk, Russia
[2]Institut National de la Recherche Agronomique, Jouy-en-Josas, France

We used a predefined COMSOL Multiphysics® interface to imitate biological growth and shape change (morphodynamics). We found a set of parameters that supply observed morphodynamics for an Arabidopsis embryo during its transition from globular to heart stage. Read More

Particle Focusing Optimization and Stress Analysis of a Magnetic Horn

S. di Luise[1], A. Rubbia[2]
[1]Swiss Federal Institute of Technology, ETH, Zurich, Switzerland and CERN European Organization for Nuclear Research, Geneva, Switzerland
[2]Swiss Federal Institute of Technology, ETH, Zurich, Switzerland

A neutrino oscillation experiment aims to the observation of the transformation of a neutrino of a given flavour into a neutrino of a different flavour. A beam of neutrinos is produced through the decay of charged pions which in turn are produced in the collision of high energy ... Read More

Modeling of Fluid Flow and Heat Transfer During a Steam-Thermolysis Process for Recycling Carbon Fiber Reinforced Polymer

A. Oliveira Nunes[1], Y. Soudais[1], R. Barna[1], A. Bounacer[1], Y. Yang[1]
[1]Centre RAPSODEE - Ecole des Mines d'Albi, Albi, France

Different types of technologies to recycle carbon fiber reinforced polymer (CFRP) waste have been studied, for example: pyrolysis, solvolysis and steam-thermolysis. The steam-thermolysis is a process that combines pyrolysis and superheated steam at atmospheric pressure to decompose the ... Read More

Modeling of Liquid Water Distribution at Cathode Gas Flow Channels in Proton Exchange Membrane Fuel Cell – PEMFC

S. Skoda[1], E. Robalinho[2], A. Paulino[1], E.F. Cunha[1], M. Linardi[1]
[1]Instituto de Pesquisas Energéticas e Nucleares, São Paulo, Brazil
[2]Universidade Nove de Julho, São Paulo, Brazil

The objective of this study is to determine the locations where liquid water accumulates at cathode gas flow channels, and the corresponding operating conditions. In such way it is possible to mitigate slug flow, responsible for channel blockage and hindering the diffusion of reactants ... Read More

Simulation of Microfabricated Linear Ion Trap

J. Heinonen[1], M. Erdmanis[1], I. Tittonen[1]
[1]Aalto University, Department of Micro- and Nanosciences, Espoo, Finland

We present a simplified 3D model that simulates the operation of a linear microscale integrated ion trap. It employs a set of metalized electrodes, which are formed on top of an insulator layer on silicon substrate. The confinement in all three dimensions is provided by the application ... Read More

Numerical Modelling of Solid Oxide Fuel Cells: Role of Various Cell Parameters on Performance

O. Ighodaro[1], K. Scott[1]
[1]Newcastle University, Newcastle upon Tyne, United Kingdom

Solid oxide fuel cells (SOFCs) are expected to play a major role in future energy systems due to their wide range of applications, high energy efficiency, environmental friendliness and good fuel flexibility. While conventional high temperature SOFCs operate at about 1000C, there is ... Read More

Modeling Melting Profiles in Chocolate Pieces for Optimizing their Sensory Properties

B. Watzke[1], F. Lenfant[1], N. Martin[1]
[1]Nestlé research Centre, Vers-chez-les-Blanc, Switzerland

Chocolate is a pleasurable product largely consumed over the world. It is known that ingredients, process and particle size distribution largely impact the chocolate sensory perceptions. It was hypothesized that a suitable choice of chocolate size and geometry modifies in-mouth melting ... Read More

Several Benchmarks for Heat Transfer Problems in COMSOL Multiphysics®

S. Titarenko[1]
[1]University of Leeds, Leeds, United Kingdom

Nowadays all branches in modern science and industry tend to solve ever complicating problems. As the result the computational time increases considerably and it become very important to reduce the processing time and use available resources more efficiently. Parallelizing problem proves ...
