§3～3 模型比尺选择与比尺效应的修正根据前节讨论,波浪运动主要受重力作用,故波浪模型按重力相似准则设计。而模型比尺大小的选择,包含因素很多,其中由于波浪在模型已被大大地缩小,原在波浪运动中的次要力,如表面张力,内摩擦力和底部摩擦力,因比尺影响使各次要力转变成为不可忽视的作用力。在模型中要同时考虑上述四种作用力的相
§3 ~ 3 Model Scale Selection and Scale Effect Correction According to the previous section, the wave motion is mainly caused by gravity, so the wave model is designed according to the gravity similarity criterion. The size of the model selection, including many factors, which because the wave has been greatly reduced in the model, the original wave movement in the secondary forces, such as surface tension, friction and friction at the bottom due to the impact of scale Each major force into a force can not be ignored. In the model, we should consider the above four phases of force simultaneously
