2. Detection of blade icing and its influence on wind turbine vibrations
Abstract : Wind turbine installations in extreme conditions like cold climate have increased over thelast few years and expected to grow in future in North America, Europe, and Asia regions due to good wind resources and land availability. Their installed capacity could reach 186 GW by the end of 2020. READ MORE

3. Improving detection and diagnosis of bearing failures in wind turbine drivetrains
Abstract : Wind power has in the last 20 years grown into one of the main sources of renewable energy in the world, with both the amount and size of the turbines increasing substantially. One of the major challenges for the wind power industry is the premature failures of especially the drivetrain components. READ MORE

4. Numerical Simulations of Turbulent Flows at Widely Different Mach Numbers
Abstract : The present thesis mainly focuses on the numerical simulation of the turbulent flow field and acoustics developed in different industrial applications. The study covers a large range of Mach numbers, starting from incompressible regimes and ending with a fully compressible flow. READ MORE

5. Computational Aeroacoustics Based on Large Eddy Simulation and Acoustic Analogies
Abstract : The thesis presents a numerical method developed by the author and its applications for computing the generated sound by an unsteady flow field and its propagation. The full equations of motion for compressible and unsteady flows describe both flow field and sound generation and propagation. READ MORE
