Abstract: Based on the special model test,the energy transtormation of flow vertical dispersion,characteris-ties of hydarul ic-jump shape, formation of whirlpool zone and the in tersecting face between upper flowand whirlpool zone are investigated.The results show:(1)changed-pool is the main cause of energytransformation;(2)hydraulic-jump shape is relevent to Z(pre-pool depth) and H(pool-ridgehigh);(3)whirlpool scope,shape and strengenth are relevent to Z,H and L(pool length);(4)intersect-ing face change show a distinct regulation,The study gives some uesful data for the waterway regula-tion and canai engineering.
Key words: hydraulic-jump shape, stage increment, whirlpool zone, intersecting face
摘要: 本文通过试验测试及研究,对流体在重力作用下产生垂向扩散过程中的能量转换过程、波状水跃的波形文化、漩滚区域的形成、面层与漩液区域交界面的确定,获取了大量的试验数据图片资料。结果表明:1.突变深潭是能量转换的主要原因;2.水跃波波形与潭前水深Z和坎高H有失;3.漩滚区域、形状、强弱与潭前水深Z、坎高H和潭长L有失;4.交界面具有明显的变化规律,以上试验研究成果对航道整治工程、人工运河渠道有一定的参考价值。
