21. Airborne Wind Energy - to fly or not to fly?
Sammanfattning : This thesis investigates crosswind Airborne Wind Energy Systems (AWESs) in terms of power production and potential role in future electricity generation systems. The perspective ranges from the small scale, modelling AWE as a single system, to the large, implementing AWESs in regional electricity systems. LÄS MER
22. MULTICOMPONENT SPRAY-TURBULENCE INTERACTION
Sammanfattning : Blended fuels are gaining importance in automotive industry owing to stringent legislations for emissions. It is important to understand the fuel spray formed as a consequence of injecting blended fuels into the engine (for direct injection engines) and also the influence of fuel spray on combustion properties.

23. Washing Machine Design Optimization Based on Dynamics Modeling
Sammanfattning : The spinning process in a washing machine is a source of undesired vibrations and noise and may cause discomfort both to the user as well as for the machine itself due to vibrations which have impact on system lifetime, reliability of operation and capacity.The aim of this thesis is to develop mathematical and computational models of a washing machine of modern type and use these models for dynamics analysis and in optimization routines to make improvements of the machine mechanical design.

24. Adhesive joining for crashworthiness : material data and explicit FE-methods
Sammanfattning : Today, crash simulations replace crash testing in the product development phase in theautomotive industry. High quality simulations enable shorter product development time andhigher competitiveness. LÄS MER
25. Industrial framework for hot-spot identification and verification in automotive composite structures
Sammanfattning : The automotive industry needs to reduce energy consumption to decrease environmental impact. This can be achieved by reducing the weight of cars, which would consequently reduce the energy consumption and emission of greenhouse gases. LÄS MER
