Book Description
Nuclear fusion is considered as a future source of sustainable energy supply. Since the H-mode discovery in ASDEX experiment "Divertor I" in 1982, the divertor has been an integral part of all modern tokamaks and stellarators. The major goal of this thesis is to develop a feasible divertor design for a fusion power plant to be built after ITER. The thesis describes the approach in the conceptual development of a helium-cooled divertor and the methods of verification and validation of the design.

On-Line Topographic Measurements of Lubricated Metallic Sliding Surfaces
Author: Spyridon Korres
Publisher: KIT Scientific Publishing
ISBN: 3731500175
Category : Science
Languages : en
Pages : 172
Book Description
Moderne Methoden wurden kombiniert, um die topographische Änderungen von gleitenden geschmierten metallischen Oberflächen on-line zu untersuchen. Die Experimente wurden mit einem neuartigen Tribometer durchgeführt, welches in-situ topographische Messungen ermöglicht. Die Ergebnisse zeigen, wie lamellare Verschleißpartikel auf gleitende Kupfer Oberflächen entstehen. Weitere Versuche ermöglichten die Entwicklung einer Näherungsmethode zur Trennung von Pflüg- und Scherbeiträge der Reibkraft.

The Effects of Internal Stress and Lithium Transport on Fracture in Storage Materials in Lithium-Ion Batteries
Author: Klinsmann, Markus
Publisher: KIT Scientific Publishing
ISBN: 3731504553
Category : Technology (General)
Languages : en
Pages : 246
Book Description
Fracture of storage particles is considered to be one of the major reasons for capacity fade and increasing power loss in Li-ion batteries. In this work, we tackle the problem by merging a coupled model of mechanical stress and diffusion of Li-ions with a phase field description of an evolving crack. The novel approach allows us to study the evolution of the Li concentration together with the initiation and growth of a crack in an arbitrary geometry and without presuming a specific crack path.

Modeling transport properties and electrochemical performance of hierarchically structured lithium-ion battery cathodes using resistor networks and mathematical half-cell models

ISBN: 373151172X
Category : Science
Languages : en
Pages : 246
Book Description
Hierarchically structured active materials in electrodes of lithium-ion cells are promising candidates for increasing gravimetric energy density and improving rate capability of the system. To investigate the influence of cathode structures on the performance of the whole cell, efficient tools for calculating effective transport properties of granular systems are developed and their influence on the electrochemical performance is investigated in specially adapted cell models.

Dynamic Model-based Analysis of Oxygen Reduction Reaction in Gas Diffusion Electrodes

ISBN: 3731512343
Category :
Languages : en
Pages : 178
Book Description
In this work, the first simulation model of oxygen depolarized cathodes (ODC), which are silver catalyst-based gas diffusion electrodes, is presented that considers the phase equilibrium of the gas-liquid interface and structure-related inhomogeneities in electrolyte distribution. By means of the model it has been identified that mass transport of water and ions in the liquid phase is a crucial factor for electrode performance and how it is influenced by the electrode structure.

Fluid Flow and Heat Transfer in Cellular Solids
Author: Ettrich, Joerg
Publisher: KIT Scientific Publishing
ISBN: 3731502410
Category : Science
Languages : en
Pages : 278
Book Description
To determine the characteristics and properties of cellular solids for an application, and to allow a systematic practical use by means of correlations and modelling approaches, we perform experimental investigations and develop numerical methods. In view of coupled multi-physics simulations, we employ the phase-field method. Finally, the applicability is demonstrated exemplarily for open-cell metal foams, providing qualitative and quantitative comparison with experimental data.

New Contributions to R-curves and Bridging Stresses - Applications of Weight Functions
Author: Theo Fett
Publisher: KIT Scientific Publishing
ISBN: 3866448368
Category : Technology & Engineering
Languages : en
Pages : 250
Book Description
Most ceramics show an increase of the crack growth resistance during crack propagation (R-curve behaviour). Reasons for such behaviour are bridging effects between opposite crack surfaces, phase transformations around the tip of a crack, and development of micro-cracking zones.This booklet predominantly deals with the bridging behaviour and the discussion of the observed effects in terms of the fracture mechanics weight function procedure.
