摘要
通航小尺度船模在港口及内河通航模拟研究中得到了广泛的应用,而相似问题是小尺度船模研究的重要环节。文中对通航小尺度船模几何相似、水动力相似、驾驶视角相似、时间比尺问题特别是操纵性尺度效应及修正办法进行了分析探讨,还对在港口及枢纽口门区等有限水域中船模试验应注意的几个问题及试验方法等方面的问题进行了讨论。
The navigable small-scale ship model is widely used in studying harbour and inland river navigable conditions and similarity is the key point. Subjects including similarity of geometric dimensions, flow dynamics, driver apparent angle, time scale, especially the operation feature dimension effect and the correction methods are studied and analysed in the paper. Several problems and testing methods that should be given due consideration in ship model testing in finite water areas in harbours and terminal entrances are also discussed.
