Hull form optimization of wave-making resistance in different speeds ...
Methods Based on the in-house hull form optimization design software OPTShip-SJTU, a luxury cruise ship is regarded as the initial hull to reduce its wave-making resistance at variable speeds.Hull form optimization based on calm-water wave drag with or without ...
In the ship design process, hull form design and optimization play an important role. In the research and engineering fields of hull form optimization…Hull form optimization of wave-making resistance in different speeds ...
Objectives For the hull line optimization design of luxury cruise ships, except for its aesthetic needs, it is of utmost important for the design and optimization of the hull form to be able to acquire resistance performance throughout the whole sailing period at variable speeds.WAVE RESISTANCE MINIMISATION IN PRACTICAL SHIP DESIGN
Free-surface potential-flow codes can provide a fast and accurate evaluation for most of the ship wave pattern. Available insight in the physics often permits to reduce the wave resistance by hull form modifications in a stepwise procedure [1,2].Chapter 7 Resistance and Powering of Ships - United States Naval Academy
The principle factors affecting ship resistance are the friction and viscous effects of water acting on the hull, the energy required to create and maintain the ship’s characteristic bow and stern waves, and the resistance that air provides to ship motion.Bulbous bow - Wikipedia
While inducing another wave stream saps energy from the ship, cancelling out the second wave stream at the bow changes the pressure distribution along the hull, thereby reducing wave resistance.Planning a Ship Hull: Core Design Parameters Explained
Form drag is closely linked to wave making: if skin friction could somehow be removed from a wide-beam hull entirely, the pressure gradients along the hull sides would increase further — generating a larger stern wave and increased wave making resistance in exchange.Suppressing thruster tunnel drag to conserve energy - DNV
Shipbuilding and hydrodynamics experts at Fincantieri and DNV have collaborated closely on a solution to address drag induced by bow thruster tunnels. It can help minimize ship hull resistance and reduce fuel consumption and carbon emissions.© 2008 - Mentions légales [ Modifiez votre fiche ] [ Inscrivez une fiche ]
