6. Information geometries in black hole physics
Sammanfattning : In this thesis we aim to develop new perspectives on the statistical mechanics of black holes using an information geometric approach (Ruppeiner and Weinhold geometry). The Ruppeiner metric is defined as a Hessian matrix on a Gibbs surface, and provides a geometric description of thermodynamic systems in equilibrium. LÄS MER
7. Plasticity Driven Damage and Void Growth
Sammanfattning : Plasticity induced damage evolution is considered using a thermodynamical approach. Different postulates on how to include the effects of damage in the constitutive equations have been studied. The results reveal that a mapping, similar to that of the stress, of both the kinematic and isotropic hardening variables is to be preferred. LÄS MER
8. Impacts of Thermo–Physical Properties on the Design, Operation, and Cost of Monoethanolamine–Based Chemical Absorption
Sammanfattning : The thermodynamic and transport properties of CO2 mixtures are essential to the design, operation, and optimization of all carbon capture and storage processes. To retrieve accurate property values, accurate property models are required. However, there are many properties, which are in turn affected by many factors. LÄS MER
9. Simulation of Phase Transformations and coarsening : Computational tools for alloy development
Sammanfattning : The final properties of an alloy are highly interlaced with its microstructure. It is therefore essential to control the evolution of the microstructure of the material during the fabrication process. Nowadays, materials design involves an increasing part of computational design to complement the traditional experimental trial and error approach. LÄS MER
10. Performance of High-temperature Coatings : Oxidation and Interdiffusion
Sammanfattning : The use of aluminiferous coatings profoundly improves the service life of superalloys but leads to the microstructural degradation of superalloys and thus the loss of mechanical properties. To solve this trade-off, two strategies were employed in this research. LÄS MER
