1. Studies of a Vertical Axis Turbine for Marine Current Energy Conversion : Electrical system and turbine performance
Sammanfattning : Ocean energy is a field of growing interest when it comes to renewable energy thanks to its high density of energy per unit area, and to the high predictability. Conversion of hydrokinetic energy, found in marine currents, is the utilization of the energy in free-flowing water for conversion to electric energy. LÄS MER
2. Engine Optimized Turbine Design
Sammanfattning : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. LÄS MER
3. 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.

4. Experimental Investigation of Performance, Flow Interactions and Rotor Forcing in Axial Partial Admission Turbines
Sammanfattning : The thesis comprises a collection of four papers with preceding summary and supplementary appendices. The core investigation solely is of experimental nature although reference and comparisons with numerical models will be addressed. LÄS MER
5. Aerothermodynamics and exergy analysis in turbocharger radial turbine
Sammanfattning : Coupling of turbomachine to reciprocating automotive engine in turbocharging leads to complex fluid flow and thermal characteristics in the turbine. Some undesirable characteristics include heat transfer, flow pulsation and secondary flow due to the complex geometry of the upstream exhaust manifold. LÄS MER
