Results for single-cornered hulls ispublished: pub divisions: UCL divisions: B04 divisions: C06 divisions: F59 keywords: surface gravity waves, wave–structure interactions note: © 2011 Cambridge University Press abstract: Consider low-speed potential flow past a ship modelled as a semi-infinite two-dimensional body with constant draught. Is it possible to design the hull in such a way as to eliminate the waves produced downstream of the ship? In 1977, Vanden-Broeck & Tuck had conjectured that a single-cornered piecewise-linear hull will always generate a wake; in this paper, we show how recently developed tools in exponential asymptotics can be used to confirm this conjecture. In particular, we show how the formation of waves near a ship is a necessary consequence of singularities in the ship’s geometry (or its analytic continuation). Comprehensive numerical computations confirm the analytical predictions. date: 2011-10 publisher: Cambridge University Press official_url: http://dx.doi.org/10.1017/jfm.2011.325 vfaculties: VMPS oa_status: green language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_source: Manually entered elements_id: 354962 doi: 10.1017/jfm.2011.325 lyricists_name: Vanden-Broeck, Jean-Marc lyricists_id: JVAND65 full_text_status: public publication: Journal of Fluid Mechanics volume: 685 pagerange: 413 - 439 issn: 0022-1120 citation: Trinh, P; Chapman, SJ; Vanden-Broeck, J; (2011) Do waveless ships exist?
