1. Stability and transition on wind turbine blades
Abstract : Transition on wind turbine blades is a highly complex phenomenon due to the myriad effects influencing the process. This thesis studies some of them, namely free-stream turbulence (FST), rotation, and three-dimensionality. The investigations employ large eddy simulations (LES) with and without (implicit or wall-resolved LES) a subgrid-scale model. READ MORE

2. On Gas Turbine Diagnostics with Emphasis on Combustion Chambers
Abstract : The thesis aims to analyse the gas turbine based energy conversion systems with the emphasis on combustion chambers. The investigation is mainly experimental at a component level. The majority of investigations concentrate on gaseous fuel firing. READ MORE

4. Constitutive modeling of a nickel base superalloy : with a focus on gas turbine applications
Abstract : Gas turbines are used where large amounts of energy is needed, typically as engines in aircraft, ferries and power plants. From an efficiency point of view it is desirable to increase the service temperature as much as possible. READ MORE

5. Processability of Laser Powder Bed Fusion of Alloy 247LC : Influence of process parameters on microstructure and defects
Abstract : This thesis is about laser powder bed fusion (L-PBF) of the nickel-based superalloy: Alloy 247LC. Alloy 247LC is used mainly in gas turbine blades and processing the blades with L-PBF confers performance advantage over the blades manufactured with conventional methods. READ MORE
