11. On Exergy and Aero Engine Applications
Sammanfattning : Aero engine performance analysis is highly multidimensional using various measures of component performance such as turbomachinery and mechanical efficiencies, and pressure loss coefficients. Using conventional performance analysis, relying on only the first law of thermodynamics, it is possible to understand how the performance parameters affect the component performance, but not how the component performance relates to the system performance.

12. Comprehensive numerical analysis of stress state in adhesive layer of joint including thermal residual stress and material non-linearity
Sammanfattning : The main objective of this work is to improve understanding of the stress state in the adhesive layer of bonded joints and identify key parameters which govern performance of adhesive joints. This information is crucial for the prediction of the failure initiation and propagation with the further estimation of the durability and strength of adhesively bonded structures. LÄS MER
13. Analysis and Evaluation of Innovative Aero Engine Core Concepts
Sammanfattning : Turbofan engines, which power the majority of the modern aircraft today, have achieved such a high maturity that small improvements of the engine performance requires a large investment. More innovative technologies, including those related to the engine cores, become increasinglyattractive due to the high fuel price in recent years as well as the strict regulations on emissions.

14. Radiative Properties and Combustion Chemistry in Oxy-Fuel Flames – Experiments and Modelling Elements
Sammanfattning : The current understanding of global warming translates into an urgent need to reduce anthropogenic CO2 emissions. Carbon capture and storage is a measure to reduce CO2 emissions and oxy-fuel combustion is emerging as one possible CO2 capture process. LÄS MER
15. Numerical Simulation of Combustion and Gasification of Biomass Particles
Sammanfattning : In this thesis, a numerical approach is adopted to study biomass thermochemical conversion. Detailed physical and chemical processes involved in the thermochemical conversion of biomass are considered. LÄS MER
