The influence of wavelength, wave steepness and bow rake angle (α) on the green water occurrence and peak pressure on a container ship deck is numerically investigated. Numerical simulations are performed using a commercial CFD solver, where a VOF method is employed to capture the free surface. The approach is validated using previously published experimental results. The time histories of the evolution of green water pressure on the deck, as well as the peak pressure magnitude, are studied at forward speed conditions. The results indicate that peak pressure due to green water increases significantly with vessel speed for all the wavelengths investigated. Investigations with a range of bow rake angle (α) indicate that the impact pressure decreases with the increase of ‘α’. For the range of ‘α’ chosen (0 degrees to 30 degrees), the differences in impact pressure are within 20% of the value for the vertical bow.

数值研究了波长，波陡度和船首前角（α）对集装箱船甲板上绿水的出现和峰值压力的影响。使用商用CFD求解器进行数值模拟，其中使用VOF方法捕获自由表面。使用先前发布的实验结果验证了该方法。在前进速度条件下，研究了甲板上绿水压力演变的时间历史以及峰值压力大小。结果表明，在所有研究的波长下，由于绿水引起的峰值压力均随着容器速度的增加而显着增加。对船首前角（α）范围的研究表明，冲击压力随着' α的增加而减小'。对于选定的“ α ”范围（0度至30度），冲击压力差在垂直弓度值的20％以内。
