Web5 de jul. de 2024 · First, we visualise the vortices shed from the hull surface using existing CFD results for the ONR tumblehome topside vessel. Then we extend Hamamoto’s slender body theory, in which the interaction between the shed vortex and the hull sections is taken into account for calm water, to the case in astern waves and apply it to the current case … Web7 de jul. de 2011 · In this research, a tumblehome vessel is selected as a typical unconventional high-speed monohull ship. The subject ship used here is the ONR tumblehome vessel which has unique characteristics, i.e. a slender body, a wave-piercing bow, a tumblehome topside, a large superstructure, and twin screws and twin rudders.
