Assessment of transient sloshing due to encounter of an LNG carrier with a steep wave
Assessment of transient sloshing due to encounter of an LNG carrier with a steep wave
This study investigates a transient sloshing flow in a rectangular tank by comparing model tests and unsteady Reynolds-Averaged Navier-Stokes CFD simulation. The sloshing flow is excited by a normally periodic surge motion, which is then subjected to a transient akin to an LNG carrier encountering a particularly steep wave. It is found that the impact pressure recorded in the transient motion is several times greater than that observed at resonance. High speed video data and CFD simulation is used to analyse the sloshing flow. The severity is explained by the absence of entrained air bubbles prior to impact and the second mode response one half period before impact.

Abstract
This study investigates a transient sloshing flow in a rectangular tank by comparing model tests and unsteady Reynolds-Averaged Navier-Stokes CFD simulation. The sloshing flow is excited by a normally periodic surge motion, which is then subjected to a transient akin to an LNG carrier encountering a particularly steep wave. It is found that the impact pressure recorded in the transient motion is several times greater than that observed at resonance. High speed video data and CFD simulation is used to analyse the sloshing flow. The severity is explained by the absence of entrained air bubbles prior to impact and the second mode response one half period before impact.
