继续沿着本系列之前论文的路线，本文通过实验解决了谐波角力作用下矩形水箱中晃动的问题。由于横向和屋顶影响与晃动评估相关并且呈现出不同的动态，因此对这些影响进行了研究。使用水和油来获得高和中等雷诺数的数据。为了解决三维流动引起的影响，还研究了罐宽度对压力统计的影响。为此，建造了一个可以通过更换侧板将其调整为 4 种不同宽度的水箱。对于流体、罐宽度和填充水平的每种组合，总共进行了 120 个实验，每个实验包含 120 个峰值，从而可以在时间域和集合域中进行分析。提供冲击压力统计数据，包括平均值、百分位数和超出概率图。
Continuing along the path of previous papers in this series, the present paper addresses, experimentally, sloshing in a rectangular tank under harmonic angular forcing. Since lateral and roof impacts are relevant in sloshing assessment and present distinct dynamics, these have been studied. Water and oil have been used in order to obtain data for high and moderate Reynolds numbers. With the aim of addressing effects induced by the three-dimensionality of the flow, a study of the influence of the tank width on pressure statistics has also been conducted. For this purpose, a tank which can be adjusted to 4 different widths by replacing the side plates was built. For each combination of fluid, tank width and filling level, a total of 120 experiments, each comprising 120 peaks, have been conducted, allowing an analysis in time and ensemble domains to be performed. Impact pressure statistics are presented including mean values, percentiles, and exceedance probability graphs.
