Modeling of Vickers indentation of TiAl alloys

G. Maizza, and R. Cagliero
Politecnico di Torino, Corso Duca degli Abruzzi 24, Torino, Italy

Instrumented indentation is increasingly used as an alternative non-destructive test method to measure mechanical properties of small volumes of materials. In this work, the instrumented indentation test is applied as a non-destructive method to assess the mechanical properties of TiAl ... Read More

Modelling Flow through Fractures in Porous Media

E. Holzbecher[1], W.L. Wah[1], and M-S. Litz[2]
[1]Georg-August Universität Göttingen, Germany
[2]Freie Universität Berlin, Germany

There are various alternative options concerning modeling fluid flow within fractures in porous media. We give a general overview, with remarks concerning the modeling using COMSOL Multiphysics. Moreover we define and study two test cases for intercomparison. Finally for one of the ... Read More

On The Modelling Of Electrowetting Using COMSOL Multiphysics

J.F. Dannenberg, J. Brinkert, and E.A.D. Lamers
Reden b.v., Hengelo (ov.), The Netherlands

One of the upcoming technologies in displays is that of the electrowetting displays. A surface can be covered by a colored oil or transparent water using a voltage to increase or decrease the wettability of the surface. A simulation of the behavior of such a thin film of oil in water, ... Read More

Deformation Behavior Of A Liquid Droplet Impacting A Solid Surface

S. Oukach[1], M. Elganaoui[1], B. Pateyron[1], and H. Hamdi[2]
[1]Laboratoire des Sciences des Procèdes Céramiques et de Traitements de Surface SPCTS, Limoges, France
[2]Laboratoire de Mécanique des Fluides et Energétique LMFE, Marrakech, Morocco

The quality of coatings obtained by means of thermal spraying depends strongly on the mechanism of the interaction between the molten droplets and the surface to be covered. The aim of the present study is to simulate the impact of a droplet onto a substrate, in order to have a good ... Read More

Pore-Scale Phase Field Model of Two-Phase Flow in Porous Medium

I. Bogdanov, S. Jardel, A. Turki, and A. Kamp
Open & Experimental Centre for Heavy Oil, University of Pau, Pau, France

Pore-scale modeling of multiphase flow through porous media is addressed most frequently to improve our understanding of flow and transport phenomena in such settings. It can be used to obtain macro-scale constitutive equations, to assign multiphase flow properties in large scale models, ... Read More

Modeling of High Temperature Superconducting Tapes, Arrays and AC Cables Using COMSOL

O. Chevtchenko
Technical University of Delft, The Netherlands

In this paper we present a set of numerical models created with COMSOL Multiphysics. The set includes quantitative models of a superconducting tape operated at 77 Kelvin, carrying a transport current and exposed to external magnetic field; an array of such tapes and a triaxial high ... Read More

Numerical Simulation of Magnetic Drug Targeting with Flow – Structural Interaction in an Arterial Branching Region of Interest

A. Morega, A. Dobre, and M. Morega
University Politehnica of Bucharest, Bucharest, Romania

We report a numerical study on the blood – magnetic carrier aggregate flow in an external magnetic field, for applications such as magnetic drug targeting. The arterial system morphology is complex and patient-related therefore more realistic numerical simulations request medical image ... Read More

Robust and Reliability-based Design Optimization of Electromagnetic Actuators Using Heterogeneous Modeling with COMSOL Multiphysics and Dynamic Network Models

H. Neubert[1], A. Kamusella[1], and T-Q. Pham[2]
[1]Technische Universität Dresden, Germany
[2]OptiY e. K. Aschaffenburg, Germany

For an exemplary electromagnetic actuator used to drive a Braille printer, a design optimization was performed. The optimization involves stochastic variables and comprises nominal optimization, robustness analysis and robust design optimization. A heterogeneous model simulates the ... Read More

Parametric Model Of An Air-Core Measuring Transformer

D. Herceg
Faculty of Technical Science, Novi Sad, Serbia

Power grid voltages and currents may be distorted due to presence of harmonics. Measurements of such voltage with harmonics may be performed using newly developed instrument with a small air-core transformer based probe as the input unit. The probe must be shielded against unknown ... Read More

Modeling of Laser Processing For Advanced Silicon Solar Cells
