Sammanfattning : The new framework of the global economy has stimulated and expanded the shipbuilding and shipping industry, especially in Asia in the twenty-first century. This induces urgent and high requirements on designing and building both conventional and new types of ships with high performance, such as high speed, manoeuvrability, seaworthiness and so on.

Sammanfattning : A waterjet propulsor operates in a different way than a conventional propeller. This makes it hard to use the same concepts for studying the thrust and powering of these systems. LÄS MER
Sammanfattning : Global market development, increasing environmental concerns and incessant risingfuel prices demand for high-grade efficient propulsion systems. This puts high pressureon the propeller designer to develop well-engineered and customized propellerdesign in a short timeframe. LÄS MER
Sammanfattning : Even if shipping is the most energy efficient and inexpensive way of transporting large volumes of goods across the world, it still could be significantly improved with respect to energy efficiency.In this thesis, propulsive efficiency is improved by moving the propeller backwards from its original position and increasing its diameter.
