2. 6. Rapid Aerodynamic Method for Interacting Sails

   Author : Karolina Malmek; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lifting line method; wind-assisted propulsion; sail–sail interaction; wingsail; wind propulsion system;

   Abstract : Rapid performance prediction tools are required for the evaluation, optimization, and comparison of different wind propulsion systems (WPSs). These tools should capture viscous aerodynamic flow effects in 3D, especially the maximum propulsion force, stall angles and interaction effects between the lift-generating units. READ MORE

4. 7. 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. 8. Energy Performance and Manoeuvring Modelling of Inland Waterway Vessels

   Author : Chengqian Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; confinement effect; inland waterways; manoeuvring prediction; autonomous vessels; ship hydrodynamics; energy efficiency;

   Abstract : 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.

6. 9. Numerical optimization of hull/propeller/rudder configurations

   Author : Kaijia Han; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel cost savings; optimization; pressure fluctuation; self-propulsion; RANS; verification and validation; cavitation; open water; lifting surface; hull-propeller-rudder; effective wake; efficiency; aspect ratio; lifting line; interaction;

   Abstract : 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.

7. 10. Marine propeller optimisation tools for scenario-based design

   Author : Ioli Gypa; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; marine propeller design; machine learning; scenario-based design; wind propulsion; interactive optimisation; user-code interaction; cavitation nuisance;

   Abstract : 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.
