  2. 1. Marine Propulsion System Performance Beyond the Propulsive Factors

    Author : Jennie Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; RANS; Energy balance analysis; Propulsor-hull interaction;

    Abstract : The marine propulsion system often operates in the wake of the ship it is mounted on. This implies that the propulsion system affects the flow around the hull, and the inflow to the propulsion system is dependent on the hull shape. READ MORE

  5. 3. Large Area Propellers

    Author : Daniel Knutsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; propeller hull interaction; propulsive efficiency; large propellers;

    Abstract : 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.
