Potential -flow and CFD investigations of bow-flare slamming on a container ship in regular heading waves

Yuan Lin et al.

Summary: The study investigates ship motions and slamming pressures of a 10,000 TEU container ship in regular waves through numerical and experimental methods. A modified model is proposed to solve symmetric and asymmetric flare slamming calculations, considering wave-ship encounter time and asymmetric rolling motions. Computational fluid dynamics simulations, empirical formulas, and segmented model tests contribute to predicting slamming behavior and duration under various conditions. The occurrence and duration of slamming are influenced by normal impact velocity, relative positions of the ship and waves, rolling period, and encountering wave, with different behaviors observed under different wave conditions.

Slamming and green water loads on a ship sailing in regular waves predicted by a coupled CFD-FEA approach

Jialong Jiao et al.

Summary: This study integrates CFD and FEA solvers to predict ship wave loads and slamming loads, taking hydroelastic effects into account. By comparing results using different mesh sizes and time step schemes, verification and sensitivity analysis of the wave loads and slamming pressures on a flexible ship are conducted. A simplified bow flare and bottom slamming pressure estimation method is proposed, based on seakeeping data of incident wave and ship global motions.
