斜鼻坎、曲面贴角鼻坎、双曲挑坎等几种异型鼻坎挑流消能工的应用研究

摘要

作为重要的消能工形式，斜鼻坎、曲面贴角鼻坎、双曲挑坎等异型鼻坎挑流消能工在工程实践中得到了广泛应用。当前在研究与设计此类消能工时，有物理模型试验与数值模拟两种方法，前者直观、可靠性较好；后者快速、灵活。两者结合的方式进行选型工作将会是事半功倍的。此类异型鼻坎消能工还有许多值得注意与研究的地方，期待能进一步发展完善。%　　As important energy dissipation types, heterotypic flip buckets such as oblique flip bucket, cured surface bucket with a block angle and double-curvature flip bucket are widely applied in engineering prac-tices. At present, there are two kinds of method in research and design of this type of energy dissipator, that is, physical model experiment and numerical simulation. The former is intuitive and more reliable, while the latter is time saving and flexible. It would be a high-efficient dissipator selection which combined both of methods. There are still many aspects on them to further study and improve.
