1. Development and Validation of a Numerical Tool for the Aeromechanical Design of Turbomachinery
Abstract : In aeromechanical design one of the major rules is to operate under High Cyclic Fatigue (HCF) margins and away from flutter. The level of dynamic excitations and risk of HCF can be estimated by performing forced response analyses from blade row interaction forces or Low Engine Order (LEO) excitation mechanisms. READ MORE

2. Sensitivity of Aeroelastic Properties of an Oscillating LPT Cascade
Abstract : Modern turbomachinery design is characterized by a tendency towards thinner, lighter and highly loaded blades, which in turn gives rise to increased sensitivity to flow induced vibration such as flutter. Flutter is a self-excited and self-sustained instability phenomenon that may lead to structural failure due to High Cycle Fatigue (HCF) or material overload. READ MORE

4. Development of Accurate Reduced Order Models in a Simulation Tool for Turbomachinery Aeromechanical Phenomena
Abstract : Modern gas turbines are still vulnerable to vibrations when operated at certain speeds. This unstable environment can lead to high cycle fatigue (HCF) and damage several of the components inside the turbine. READ MORE

5. Lighting candles before a headless Jesus : sacred heritage, heritagized sacredness, and the many journeys between categories
Abstract : The overarching aim of this thesis, situated within Museology and Heritage Studies, is to investigate the different modes and devices of transfer between sacredness and heritage. The research question, 'What happens in the transfer between heritage and sacredness?', is investigated as production of sacred heritage in early modern Europe and specifically Sweden, Rome, and Venice (Part I), and as uses of the sacred as heritage in different times and contexts (Part II).
