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

G. Maizza, and G. Lorenzatto
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

Numerical Sensitivity Analysis of a Complex Glass Forming Process by Means of Local Perturbations

C. Janya-Anurak, T. Bernard, and H. Birkenhofer
Fraunhofer Institute of Optronics
System Technologies and Image Exploitation IOSB
Karlsruhe, Germany

Over the last few years, Finite Element Models have become increasingly important as tool for the design of process control strategies or process optimization. Some processes possess complex spatio-temporal coupled and nonlinear dynamic. For process optimization it is very important to ... Read More

Computational Fluid Dynamics Simulations of an Innovative System of Wind Power Generation

S. Carcangiu, A. Fanni, and A. Montisci
Department of Electric and Electronic Engineering
University of Cagliari
Cagliari, Italy

In this work an innovative wind power generation in urban areas is proposed. The generation system substitutes the roof of the building and it consists of a static part, the stator, and a moving part, called impeller, which is a centripetal turbine with vertical axis of rotation. Since ... Read More

Simulation Enquiries on Energy Transfer Efficiency in Stored Fluids

E. Zinterl, and G. Jakopic
JOANNEUM RESEARCH Forschungsgesellschaft mbH,
MATERIALS-Institute for Surface Technologies and Photonics
Weiz, Austria

Heating or cooling of stored fluids by thermal energy exchange with the enclosing walls may be enhanced by improving the efficiency of energy transfer; energy loss to the ambient is equalized for all simulations. Buoyancy driven internal natural convective flow is assumed to be the main ... Read More

Modelling and Simulation of a Three-stage Air Compressor Based on Dry Piston Technology

M. Heidari, and P. Barrade
EPFL
Lausanne, Switzerland

The core of this modelling is to study heat transfer and fluid dynamics processes for a compression expansion system, and the main particularity is that heat transfer and air movement are due to the movement of the piston. We have implemented a \"moving mesh\" solver to compute the ... Read More

High Frequency Magnetohydrodynamic Calculations in COMSOL

N. Kleinknecht, and S. A. Halvorsen
Teknova AS
Kristiansand, Norway

In many metallurgical processes metals are (heated and) stirred by an oscillating external magnetic field. The magnetic field induces electric currents in the metal and the currents interact with the magnetic field to create a force, the Lorentz force. For high frequencies induction only ... 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

Three Dimensional Numerical Study of the Interaction of Turbulent Liquid Metal Flow with an External Magnetic Field

G. Pulugundla[1], M. Zec[2], and A. Alferenok[3]
[1]Institute of Thermodynamics and Fluid Mechanics, Ilmenau University of Technology, Ilmenau, Germany
[2]Department of Advanced Electromagnetics, Ilmenau University of Technology, Ilmenau, Germany
[3]Electrothermal Energy Conversion Group, Ilmenau University of Technology, Ilmenau, Germany

Lorentz Force Velocimetry (LFV) is a non-contact measurement technique used to determine flow rates in electrically conducting fluids by exposing the flow to an external magnetic field and measuring the Lorentz force acting on the magnet system. Typically, for LFV applications real and ... Read More
