Abstract
A detailed description of the flooding process is crucial to analyze the complex hydrodynamic behaviors and enhance the survivability of the damaged ship. In this paper, through establishing three typical damage scenarios with various locations, the commercial software CD Adapco STAR-CCM+ based on the Reynolds-Averaged Navier-Stokes (RANS) solver is applied to simulate the flooding process involving multiple compartments. The basic computational fluid dynamics (CFD) models and specific simulation settings are elaborated. The volume of fluid (VOF) method combined with the user defined field function is developed to distribute the initial free surface. The captured flooding process indicates that the air compression due to the restricted ventilation decreases the flooding amount. The obtained flooding time can provide necessary data to support for appropriate rescue management and evacuation options.
Highlights
In the last decades, a large number of ship accidents continue to occur regardless of how a ship is designed, constructed and operated
The flooding process can be mainly divided into three phases: The transient stage, the progressive stage, and the steady stage
The complex dynamics and fluid-structure interaction has a strong effect on the stability of the ship, making the ship sink rapidly or even capsize
Summary
A large number of ship accidents continue to occur regardless of how a ship is designed, constructed and operated. When the ship is damaged, the motion of fluid into the flooded compartments is violent and complex. The complex dynamics and fluid-structure interaction has a strong effect on the stability of the ship, making the ship sink rapidly or even capsize. This stage lasts only a couple of roll cycles and is referred to as the transient stage, according to IMO SLF46/INF. (2003) [2]. After this stage, the progressing flooding tends to be quasi-stationary and flows through internal openings to other compartments. The hydrodynamic problem in the flooding process has been a major issue as summarized in the last several International Towing Tank Conference (ITTC) Stability in Waves Committee Reports [5,6]
