Simulação Fluidodinâmica de um Digestor Contínuo para Produção de Celulose.

I. Neitzel [1], R. Kreczkiuski [1],
[1] FATEB, Telemaco Borba, Paraná, Brasil

A obtenção de polpa celulósica antecede a produção de papel e envolve a separação das fibras da madeira mediante a utilização de energia mecânica, térmica, química ou a combinação desses processos. Esta operação é realizada em um reator, tubular, cilíndrico e vertical (tipicamente 6 m de ... Mehr lesen

Optimization of Welding Parameters using 3D Heat and Fluid Flow Modeling of Keyhole Laser Welding

[2] LUniv. Bretagne-Sud, Lorient, France

A Laser-welded blank (LWB) consists of steels of different thicknesses and/or grades welded together to produce a single blank prior to the forming process. LWB are mostly used in the automotive field where the high productivity of the laser welding process is an advantage. Numerical ... Mehr lesen

Development of COMSOL-Based Applications for Heavy Oil Reservoir Modeling

S. Cambon [1], I. Bogdanov [1]
[1]Open & Experimental Center for Heavy Oil (CHLOE), University of Pau, Pau, France

The efficiency and environmental impact of oil production become a principal challenge of energy producing companies. The improvement of existing and development of novel methods are often feasible within either a “new” physical framework (from the viewpoint of oil reservoir ... Mehr lesen

Simulation and Verification of Bionic Heat Exchangers with COMSOL Multiphysics® Software

A. Kremers [1], M. Pieper [1]
[1] Applied University Aachen, Aachen, Germany

Bionics is the scientific discipline between biology and technology. The aim of bionics is to recognize natural design principles and derive technical solutions. Natural structures have been optimized over generations by evolution. In most cases the minimization of the energy demand is a ... Mehr lesen

Simulation Tests of the Constitutive Equation of a Nonlinear Viscoelastic Fluid

[1] University of Szeged, Szeged, Hungary
[2] Kecskemét College, Kecskemét, Hungary

The determination of the constitutive equation of a nonlinear viscoelastic fluid is a challenging task, especially if a space-dependent equation is needed [1]. In this contribution, we present simulations of certain rheometry tests of a high-viscosity nonlinear viscoelastic fluid with a ... Mehr lesen

Optimization of the Supersonic Gas Jets' Parameters for In-Gas-Jet Nuclear Spectroscopy Studies

A. Zadvornaya [1], Y. Kudryavtsev [1],
[1] KU Leuven, Leuven, Belgium

The in-gas-jet laser ionization and spectroscopy method (Figure 1) that has been developed at KU Leuven allows to produce and to perform laser spectroscopy of short-lived radioactive isotopes created in different types of nuclear reactions [1,2]. To realize the advantages of in-gas-jet ... Mehr lesen

Topology Optimization of Thermal Heat Sinks

[1] Technical University of Denmark, Roskilde, Denmark
[2] Technical University of Denmark, Kgs. Lynby, Denmark

Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in [3] for forced convective heat transfer and in [4] for natural convection ... Mehr lesen

Studying PEM Fuel Cells using Equation Based Simulation

J. Blackburn [1], N. McCartney [1],
[1] National Physical Laboratory, London, UK

We present computer simulation results for PEM fuel cells using COMSOL Multiphysics® software. We have developed novel PDE equations at NPL from first principles and these are more realistic than models typically used in literature. The theory includes Maxwell-Stephan and Nernst-Planck ...

A Numerical Euler-Lagrange Method for Bubble Tower CO2 Dissolution Modeling

D. Legendre [1], R. Zevenhoven [1],
[1] Åbo Akademi University, Turku, Finland

While the processes taking place in a bubble reactor are simple to describe in a few sentences it is much more difficult to give a physical description that is useful for engineering purposes. A better understanding of a cluster of bubbles dissolving in a liquid where the species ... Mehr lesen
