17 lut 2020 · The data show distinct trends of convergent evolution across the entire range of sizes, namely: (i) the proportionality between beam and draft, (ii) the proportionality between overall boat...
1 cze 2020 · The correlation of the calculated and experimental curves confirms the validity of the described hydrodynamics of residual resistance. This article is intended for specialists in the field of hydrodynamics of displacement vessels and for designers of the ship hull.
1 cze 2020 · residual resistance of vessel displacement is the result of the formation of retaining bow waves, Kelvin wave systems and their interaction—as well as the action of viscosity, which is...
1 lut 2008 · Wind power. Moving air has kinetic energy that can, through its interaction with the sails, be used to propel a sailboat. Like airplane wings, sails exploit Bernoulli’s principle. An airplane wing is designed to cause the air moving over its top to move faster than the air moving along its undersurface.
paper presents a part of the research on the application of full-scale CFD simulations into ship design and operation for increasing energy efficiency, comfort and safety of ships. In Section 3, the case study vessels were described.
1 lut 2022 · In this research, we investigated the critical parameters in a high-speed vessel to reduce the drag coefficient of the wet surface area.
1 paź 2013 · The sum of the ITTC friction drag and the NM wave drag can then be expected to yield realistic practical estimates that can be useful for routine applications to design and hullform optimization of a broad range of displacement ships.
