摘要
通过1个高水头台阶式退水渠的设计,计算分析对比5个常用的公式对台阶式溢洪道消能效率结果的差异,以及各个公式的适用条件。在台阶式泄水槽的设计时,可以先通过经验公式的结果进行尺寸设计,然后用三维3DCFD验证。通过三维FLOW3D计算的验证,说明退水渠台阶消能及消力池的设计是合理的。
The difference of the stepped spillway energy dissipation efficiency results obtained from calculation by 5 common formulas respectively and the applicability conditions of each formula were analyzed and compared based on the design of a high water head stepped discharge channel. When a stepped discharge channel is designed, its dimensions can be first designed according to the results calculated using an empirical formula and then verified by 3DCFD. The verification by FLOW 3D calculation indicates that the design of both discharge channel stepped energy dissipation and plunge pool proved rational.
