【摘要】 本文根据实测的实验资料,论述了静止均匀环境中淹没铅直射流的横断面流速分布及其轴线速度的变化规律。对射流核长度、射流扩散角与出口弗劳德数、淹没水深之间的关系进行了探讨。并将上述成果与国内外的实验、数值计算的成果进行了对比。更多还原

【Abstract】 In this paper the velocity distribution in the cross section and the axial velocity variation of vertical jet flow in statical and uniform enviroment were studied by means of experiment. The relations among the length of the core region, the diffusion angle and the froude number and the submerged depth were also studied. Our results were compared with experimental and numerical results, and it shows that our results are reasonable.更多还原
