2015

Vol. 33, iss. 1

69--80

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.

The dynamic free surface effect for different locations of partly filled tanks on board ships

nr 1

171-179

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.
