摘要
通过１：４０模型试验以及与１：５模型的对比试验研究了由若干喷嘴射流所合成的流场的相似规律，得出了流场相似参数以及流场基本自模的结论．对于木材在流场中漂送时的相似问题，亦作了定性分析，提出了木材漂送相似准数及与其所受水动力系数之间的关系，指出了木材漂送问题的相似要求．
The similarity law on the jet flow formed by several nozzles is studied by means of experiment on both 1: 40 and 1: 5 models in this paper. On the basis of comparative analysis,a similarity number for the jet flow fields is defined and a conclusion on the self-similar flow field is obtained. Meanwhile,the paper analyses the similarity of log floating,presents a relationship between the similarity number and the hydrodynamic coefficients and points out some requirements for the similarity.
