摘要
研究了收缩段出口顶壁型式对表面波的影响,得到了最佳的出口设计,并分析了满流和明流情况下,流场速度、湍流度等沿程的发展变化.
The effect of contraction exit upward type on surface waves has been investigated, and the optimum exit design is obtained. In addition, the developments of flow velocity and turbulence intensity are analysed for closed flow and open channel flow .
