16. There Is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano
Sammanfattning : Mixing different chemical species and decreasing dimensions to the nanoscale are two powerful approaches for improving materials. In both cases new properties emerge, and structure, composition, and chemical ordering can be tuned to tailor materials for specific purposes. LÄS MER
17. CFD Modeling of Turbulent Flows in Industrial Applications with Emphasis on Premixed Combustion in Gas Turbines
Sammanfattning : Increasing restrictions on hazardous emissions combined with demands for good profitability from the operators in the energy market have contributed strongly to the development of innovations in which the emphasis is on low emissions and high efficiency. For gas turbine-based power plants, emission of NOx in particular is governed by stringent legislation. LÄS MER
18. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors
Sammanfattning : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. LÄS MER
19. Thermodynamic characterization of superconducting and magnetic materials using nanocalorimetry
Sammanfattning : Measurement of specific heat is a powerful technique for the investigation of novel materials. Superconducting and magnetic systems, in particular, can be thoroughly characterized by studying their electronic contribution to the specific heat. LÄS MER
20. Numerical Investigation of Some Heat Transfer Topics with Relevance to Gas Turbines
Sammanfattning : The first part of the investigation is related to the heat transfer and fluid flow problem inside ribbed ducts with a square cross section. The typical applications of this problem are in the cooling of gas turbine blades and guiding vanes. The second part is related to application of intercoolers in gas turbine systems. LÄS MER
