The aim of this study is to investigate the influence of electro-magnetic stimulation on bone regeneration and the effect on bacterial infection. Electro-magnetic stimulation is a promising technique and a powerful tool for the enhancement of bone regeneration. To optimize the amplitude ... En savoir plus

Thermomechanical Design of a Gas Turbine Reheat Combustor Experiment Using FEM Analysis with the COMSOL Multiphysics® Software

F. M. Berger [1], M. Eser [1], T. Sattelmayer [1],
[1] Lehrstuhl für Thermodynamik, Technical University of Munich, Munich, Germany

Enhanced operational flexibility and low levels of pollutant emissions are achieved with a sequential arrangement of premixed combustion stages in gas turbines for power generation. In the second – reheat – combustion stage, hot flue gases of approximately 1500K are enriched with fuel ... En savoir plus

Finite Element-Based Characterization of Viscoelastic Materials

X. Song [1], S. Dircks [1], D. Mirosnikov [1], B. Lassen [2],
[1] Mads Clausen Institute, SDU, Sønderborg, Denmark
[2] DONG Energy, Fredericia, Denmark

The objective of this study is to acquire a full characterization of a hyper-elastic material. The process is realized by performing a Dynamic Mechanical Analysis (DMA) with a viscoelastic material, which is extended by image processing algorithms in order to measure the changing ...

Numerical Modeling of Subsurface CO2-Storage

E. Holzbecher [1],
[1] German University of Technology in Oman (GUtech), Halban, Oman

A model for CO2 storage is presented. It is shown that the system is highly dynamic, i.e. results depend strongly on parameter disturbances and numerical features. However, a series of scenario calculations shows that there are invariants, most important: the duration of the early ... En savoir plus

Implementation of a Modified Anisotropic Creep Model for Clays with Use of the Physics Builder

M. Karlsson [1], J. Yannie [1],
[1] Chalmers University of Technology, Gothenburg, Sweden

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user ... En savoir plus

Tunnels, a New Potential Source of Energy: 3D Modeling of a Heat Exchanger within Tunnel Lining

C. Soussi [1], O. Fouché [2], G. Bracq [3], S. Minec [3],
[1] Le Cnam, Paris, France
[2] Ecole des Ponts, Champs-sur-Marne, France
[3] Bouygues Construction, Saint-Quentin-en-Yvelines, France

This work investigates the possibility of thermal activation of future tunnels to heat and/or cool the surface buildings or infrastructure such as subways stations. The principle is to insert pipes in the tunnel lining segments, which are connected to a geothermal pump. A heat transfer ... En savoir plus
