Opis:: The results of experimental research and numerical simulation of sloshing phenomenon are presented. The heeling moment due to the dynamic movement of the fluid in a partly filled ship's tank is computed. The dependence of heeling moment effects upon the locations of the tank in the hull is described.
W artykule przedstawiono wyniki badań eksperymentalnych i symulacji numerycznych w zakresie przebiegu momentu przechylającego statek wskutek ruchu cieczy w niepełnych zbiornikach. Uwagę zwrócono na wpływ położenia niepełnego zbiornika względem osi kołysań bocznych statku.

Opis:: The paper has been presented criteria of similarity between of liquid motion. Results of initial research on air flow’s dynamic impact on a ship model of 888 project type are presented in the elaboration as well. The research has been executed at a test stand located in the Polish Naval Academy. The ship model of 888 project type has been an object of the tests. Results of executed measurements have been compared with theoretical calculations for an angle of dynamic heel. Input parameters for the tests and calculations have been defined in accordance with recommendations of Polish Register of Shipping (PRS) and IMO (IMO Instruments). Determination of a heeling moment by wind operation has been a key issue.

Tematy:: maritime transport

Opis:: According to some authors it is estimated that around 80% of accidents at sea are caused by human and organizational errors (HOE). In order to gain knowledge of phenomena that occur during ship operations, a decision was made to design and build a test site for carrying out model-based investigations of ships, including in situations of hazard to buoyancy. The model-based investigations are used as the basic and universal method for forecasting ship dynamic properties. The results of initial research on the dynamic impact of air flow on an 888 project type ship model are presented in the elaboration. The research has been executed at a test stand located in the Polish Naval Academy. The experimental results have been compared with theoretical calculations for angle of dynamic heel. Input parameters for the tests and calculations have been defined in accordance with recommendations of the Polish Register of Shipping (PRS) and International Maritime Organization (IMO) (IMO Instruments).

Tytuł:: A Method of Assessment of the Liquid Sloshing Impact on Ship Transverse Stability
Autorzy:: Krata, P.
Powiązania:: https://bibliotekanauki.pl/articles/117159.pdf
Data publikacji:: 2014
Wydawca:: Uniwersytet Morski w Gdyni. Wydział Nawigacyjny
Tematy:: ship operation
liquid sloshing phenomenon
liquid sloshing
computational fluid dynamics (CFD)
hydrodynamics
ship stability
ship transverse stability
dynamic heeling moment
Opis:: Liquid sloshing phenomenon taking place in partly filled ships’ tanks directly affects the stability of a vessel. However, only static calculations are carried out onboard ships nowadays and static transfer of liquid weight is taken into account in the course of routine stability calculation. The paper is focused on a dynamic heeling moment due to liquid sloshing in tanks onboard ships. The set of numerical simulations of liquid sloshing taking place in moving tanks is carried out. The realistic range of geometric parameters is taken into account. The conducted CFD simulations are experimentally verified. Finally, the method of an assessment of the liquid sloshing impact on ship transverse stability is worked out. The key point of the method is a dynamic coefficient describing relation of the researched dynamic heeling moment and the quasi-static one in terms of dynamic stability of a vessel which is related to the weather criterion of ship stability assessment.
