21. Multimethod aerodynamic research of engine-realistic turbine rear structures
Sammanfattning : Despite the significant advancements in aircraft engine technology over the past years, the aerodynamics of engine-realistic turbine rear structures (TRS) remain largely unexplored. The TRS, a structural and aerodynamic component situated downstream of the low-pressure turbine (LPT), plays a pivotal role in engine aerodynamic performance, deswirling the LPT flow to maximize the engine thrust.

22. Fundamental Experimental and Numerical Investigation Focusing on the Initial Stage of a Top-Blown Converter Process
Sammanfattning : The aim of this thesis work is to increase the knowledge of phenomena taking place during the initial stage in a top blown converter. The work has been done in a few steps resulting in four different supplements. Water model experiments have been carried out using particle image velocimetry (PIV) technology. LÄS MER
23. Maintenance optimization for power distribution systems
Sammanfattning : Maximum asset performance is one of the major goals for electric power distribution system operators (DSOs). To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. LÄS MER
24. Optical manipulation and heating of gold nanoparticles near interfaces
Sammanfattning : By focusing laser light to small volumes, its momentum can be used to trap and manipulate objects in the size range from cells down to single atoms. Devices using this effect are called optical tweezers, and have found use in measuring and applying minuscule forces and torques, contributed to deepening our knowledge of molecular motors, unraveling the mechanics of cells and DNA, and better understand statistical mechanics and hydrodynamic interactions at the nanoscale.
