  • 摘要: 由于葛洲坝工程的修建,中华鲟的洄游路线被阻断了,使中华鲟产卵场由过去的屏山至木洞800 km江段压缩至现在的葛洲坝下游不足5 km江段。中华鲟也由水产资源演变成一级保护动物。运用水动力学的N-S方程和k-ε紊流数值模型,结合计算水气两相流的方法VOF(volume of fluid),采用控制体积法离散计算区域,对葛洲坝下游中华鲟产卵河段的流场进行了计算。并结合中华鲟的生态特性,分析其产卵繁殖对流场特性的要求,以期在三峡水库下游河道整治中注意保护其产卵场地。
    Abstract: The Chinese sturgeon,Acipenser sinensis,is an anadromous protected species that presently only spawns in the Yangtze River. It is also the important fishery resources. Its migration pattern is blocked due to the Gezhouba projects,so the length of natural spawning site has reduced from 800 km to less than 5 km,thus,it becomes the extra-protected animal. In this article,the ecological-hydraulics models is established to simulate and analyze the 3-D flow character by using the N-S and the k-ε formulas,the method of volume of fluid is also used to simulate the two phase flow,and the finite volume method is used to disperse the calculated area,which aims to provide technical parameters for the optimizing regulation of Three Gorges reservoir.
