Dynamic Heeling Moment Due to Liquid Sloshing in a Rectangular Tank of Different Dimensions and Elevation in Ship’S Hull / Dynamiczny Moment Przechylający Od Swobodnych Powierzchni Cieczy W Prostokątnym Zbiorniku Okrętowym O Różnych Wymiarach I Lokalizacji Pionowej

Abstract

Abstract Liquid sloshing phenomenon taking place in partly filled ships’ tanks directly affects the stability of a vessel and her safety on seaway, however, only static calculations are carried out onboard ships nowadays. The presented investigation is focused on dynamic approach towards liquid motion onboard ships. The set of numerical simulations of liquid sloshing taking place in moving tanks is carried out in terms of tank’s dimensions and its elevation within ship’s hull. A number of characteristics of the heeling moment due to liquid sloshing is obtained and analyzed.
