Coupling between ship motion and sloshing using potential flow analysis and rapid sloshing model
Coupling between ship motion and sloshing using potential flow analysis and rapid sloshing model
The coupled motion of a rigid barge with a partially filled tank is
studied with a pulsating Green’s function approach, Rankine source method and a Rapid Sloshing Model (RSM). The aim of this paper is the comparison of the suitability of potential flow based methods and RSM, based on RANS, in simulating the fundamental physical aspects of liquid sloshing and their application to the coupling between sloshing and ship motion. The hydrodynamic forces and moments associated with the liquid sloshing are represented by relevant added mass coefficients. Subsequently, the coupled equations of motion of ship-partially filled tank in regular beam waves are solved.
Comparison of hydrodynamic characteristics of liquid sloshing (e.g.added mass) and ship motions obtained using the aforementioned methods indicate good overall agreement with other available numerical predictions and experimental measurements. All the methods used here capture well the physical aspects of the effects of sloshing liquid on ship motions.

Abstract
The coupled motion of a rigid barge with a partially filled tank is
studied with a pulsating Green’s function approach, Rankine source method and a Rapid Sloshing Model (RSM). The aim of this paper is the comparison of the suitability of potential flow based methods and RSM, based on RANS, in simulating the fundamental physical aspects of liquid sloshing and their application to the coupling between sloshing and ship motion. The hydrodynamic forces and moments associated with the liquid sloshing are represented by relevant added mass coefficients. Subsequently, the coupled equations of motion of ship-partially filled tank in regular beam waves are solved.
Comparison of hydrodynamic characteristics of liquid sloshing (e.g.added mass) and ship motions obtained using the aforementioned methods indicate good overall agreement with other available numerical predictions and experimental measurements. All the methods used here capture well the physical aspects of the effects of sloshing liquid on ship motions.
