摘要
对管涌现象国内外发展的现状作了总结,详细的归纳了管涌的总水头法、临界水力梯度等计算法和管涌的室内试验和数值模拟的成果。基于先进的数码摄像可视化跟踪技术和数字信息计算机实时处理技术以及散体颗粒流软件(PFCZD)技术,对未来管涌现象的研究做了展望。
Based on the summarization of the current piping phenomenon research both at home and abroad, in this paper, the calculation methods of total head and Critical Hydraulic Gradient and the results of lab experiment and numerical simulation on piping are summed up in detail. In this paper, some expectations are also made about the future research of piping phenomenon according to the advanced digital photographic video tracing technique, computer real time digital information processing technique and PFC2D technique.
