AI Technical Summary
The lack of existing CFD simulation technology that comprehensively considers the coupled response of liquid cargo ship hull motion and liquid tank sloshing leads to inaccurate prediction of liquid cargo ship motion in waves, affecting transportation safety.
The CFD numerical simulation method is adopted. By establishing the geometric model of the hull and liquid tank, setting up the numerical water tank fluid domain and performing mesh generation, enabling the dynamic fluid-object interaction function, determining the liquid tank loading rate and initial conditions, performing numerical solution and data monitoring, and outputting simulation results.
It realizes the coupled response simulation of external and internal flow fields of liquid cargo ships in waves, and provides comprehensive information on incident waves, hull motion, fluid flow in the tank and pressure load of liquid tank sloshing, thereby improving the accuracy and safety of liquid cargo ship design and development.
