Study of unsteady hydrodynamic effects in the ship stern area under shallow water conditions: = Untersuchung der instationären hydrodynamischen Effekte im Heckbereich eines Schiffes im Flachwasser Untersuchung der instationären hydrodynamischen Effekte im Heckbereich eines Schiffes im Flachwasser Shevchuk, Ivan , 1985- (VerfasserIn) Kornev, Nikolai , 1960- (GutachterIn) Moctar, Bettar Ould el (GutachterIn) Universität Rostock (Grad verleihende Institution) Universität Rostock Fakultät für Maschinenbau und Schiffstechnik (Grad verleihende Institution) Text theses Text Hochschulschrift 2016 2016 eng electronic resourceremoteComputermedienOnline-Ressource1 Online-Ressource The operating conditions of inland cruise vessels include small water depths, which in combination with typically high block coefficients lead to rise of parasitic vibration in the ship stern. This effect impairs the habitability and thus has to be studied so as to propose some measures of its suppression. In the present work the CFD analysis of the flow at the stern of a cruise vessel was conducted using scale-resolving simulation. Influence of different factors on the statistics of the velocity field, propeller forces, pressure oscillations and cavitation inception regions was studied.<eng> vorgelegt von Ivan Shevchuk aus Rostock Dissertation Universität Rostock 2016 Heck Instationäre Strömung Flachwasser 623.81243 623.8 620 ZO 6220 50.33 55.40 http://rosdok.uni-rostock.de/resolve/urn/urn:nbn:de:gbv:28-diss2018-0037-3 https://doi.org/10.18453/rosdok_id00002043 https://nbn-resolving.org/urn:nbn:de:gbv:28-diss2018-0037-3 https://d-nb.info/1293651850/34 Study of unsteady hydrodynamic effects in the ship stern area under shallow water conditions--(DE-627)877856540 urn:nbn:de:gbv:28-diss2018-0037-3 doi: 10.18453/rosdok_id00002043 oclc: 1030991686 ppn: (DE-627)1018347038
