摘要
对比分析国内外传统船闸门类型及其水动力特性,从物理模型、原型观测、数值模拟3方面总结国内外人字闸门水动力特性研究进展,指出研究过程中的关键技术难题——闸门动水阻力矩的变化规律,建议进一步关注闸门启闭过程中水流流态及流场变化、动水压力变化规律,整合并综合分析不同闸门阻力矩原型观测成果,改善闸门启闭数值模拟过程中边界条件处理方式及自由水面捕捉精度,尝试在定性分析的基础上对水阻力矩产生机理有定量的认识。
This paper compares the types and hydrodynamic characteristics of navigation lock gate, summarizes the research progress in hydrodynamic characteristics of miter gate at home and abroad from aspects of physical model, prototype observation and numerical simulation, and illustrates the variation characteristics of miter gate＇s operating torque. It is suggested to pay more attention to the variation law of flow pattern ＆ flow field, and the hydrodynamic pressure during the movement of miter gates. The rich results from prototype observation of different kinds of miter gates should be integrated and analyzed synthetically. The processing of boundary condition and free surface should be handled correctly to improve the simulation precision. It is of great significance to get the quantitative understanding on the generation mechanism of resistant torque caused by water based on the qualitative analysis.
