11. NOx Abatement Technique for Marine Applications - Improved SCR Systems
Sammanfattning : Growing awareness of the environmental implications of emissions of nitrogen oxides (NOX), such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOx legislations within the framework of IMO, with the most stringent legislation, Tier III, representing a NOx reduction of approximately 80% compared with today’s engines. Several NOx abatement technologies are available on the market, the most effective of which may be Selective Catalytic Reduction (SCR). LÄS MER
12. Automation of underwater operations on wave energy converters using remotely operated vehicles
Sammanfattning : In the last fifteen years, the Division of Electricity at Uppsala University has been developing a wave energy converter (WEC) concept. The concept is based on a point-absorbing buoy with a directly driven linear generator placed on the seabed. LÄS MER
13. Propeller-Hull Interaction Effects in Calm Water and Regular Head Waves
Sammanfattning : In order to design fuel-efficient ships and install compatible propulsion systems, ship and propeller designers need to know the potential effects of the interactions between different ship components, e.g., hull, propeller, appendages and machinery, on the ship performance at sea.

14. Energy Performance and Manoeuvring Modelling of Inland Waterway Vessels
Sammanfattning : Inland waterway transport has significant potential to reduce greenhouse emissions and road congestion safely and sustainably. To construct competitive, intelligent waterborne transport networks, the use of advanced vessels with clean energy and a high degree of automation or autonomy is an ideal solution for next-generation transport.

15. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction
Sammanfattning : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.
