摘要
在整理国内外研究成果的基础上,对弯道急流冲击波研究现状进行了概述,介绍了理论计算和数值模拟的研究进展及存在问题,论述了弯道急流冲击波的多种消减措施并剖析其利弊。指出陡坡弯道急流的计算方法仍需完善,管道中的弯道急流冲击波问题是国内研究的盲点,值得学者们关注,弯道急流冲击波的三维数值模拟和消减措施有待更深入的研究。
Based on review of worldwide research, research achievements of supercritical flow shockwave in bends are summarized and analyzed. Firstly, development and problems of theoretical calculation and numerical simulation are introduced. Moreover, reduction methods of shockwave and their characteristics are discussed overall. It is pointed out that the effects of bottom slope and transverse slope on supercritical flow in bends should he systematically investigated, supercritical flow shockwave in bend manhole which drew little attention deserved a major concern, three-dimensional numerical simulation and reduction method of supercritical flow shockwave in bends should be researched deeply.
