21. Flow over rough surfaces, and conjugate heat transfer, in engineering applications
Sammanfattning : This thesis focuses on two important topics in the field of fluid mechanics and heat transfer that were treated separately. On the one hand, the flow over rough surfaces, which is not yet completely understood, despite of the fact that it has an important implication in many engineering applications, especially in the naval industry for ships and boats because the friction drag caused by fouling, antifouling coatings and roughness in general impacts the fuel consumption and toxic emissions to the atmosphere.

22. Influence of deformation and environmental degradation of Inconel 792
Sammanfattning : Industrial gas turbines are often used as a mechanical drive for pumps and compressors or in power generation as an electric power supply. The gas turbine has for many years been a popular engine due to its flexibility with respect to different types of fuel and due to a design, that enables a high power-to-weight ratio. LÄS MER
23. Modeling Diesel spray combustion using a Detailed Chemistry Approach
Sammanfattning : The rapid development of computer hardware during the past decade has contributed substantially to advances in almost all branches of science. Computer modeling is being applied to increasingly small physical scales and increasingly large domains, facilitating the generation of advanced phenomenological models and models based on first principles.

24. Assessment of bio-based fuel ash effects on magnesia refractory materials in quicklime production kilns
Sammanfattning : Limestone is calcined into quicklime in lime kilns at temperatures above 1000°C. Heat is supplied through combustion inside the kilns, which are insulated with a lining of refractory bricks to mitigate heat loss and to protect the kiln from the hot, chemically aggressive, and mechanically abrasive environment.

25. Modelling and optimization of gear shifting mechanism, Application to heavy vehicles transmission systems
Sammanfattning : Without an efficient transmission system the idea of an efficient vehicle is incomplete. During running of the vehicle especially in case of heavy vehicles the transmission system has to face different situations during which the system possibly can lose its efficiency. LÄS MER
