1. Interactive Optimisation in Marine Propeller Design
Sammanfattning : Marine propeller design is a complex engineering problem that depends on the collaboration of several scientific disciplines. During the design process, the blade designers need to consider contradicting requirements and come up with one optimal propeller design as a solution to the specific problem. LÄS MER
2. Marine propeller optimisation tools for scenario-based design
Sammanfattning : The marine propulsion system is one of the most important components of a ship in order to cover the demanding operating needs of propulsion nowadays and to increase performance in a wide range of operating conditions. Marine propellers are designed with the purpose of matching the hull and machinery system, create the required thrust for the entire operational profile, and fulfil the techno-economical requirements that depend on the decision-making of several stakeholders.

3. Marine Propeller Optimisation - Strategy and Algorithm Development
Sammanfattning : Recent trends in the shipping industry, e.g., expanded routing in ecologically sensitive areas and emission regulations, have sharpened the perception of efficient propeller designs. Currently, propeller efficiency, estimated fuel consumption and, more often, propeller-radiated noise are parameters that steer the business Zeitgeist. LÄS MER
4. A Generic Model for Simulation of the Energy Performance of Ships - from Early Design to Operational Conditions
Sammanfattning : Forecasts show a doubling of the world’s transportation needs until 2050. Shipping today accounts for 90% of all freight transport. Simultaneously, shipping must become cleaner and more energy-efficient to meet the target to more than halve 2005 greenhouse gas emissions by 2050. LÄS MER
5. 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.
