| 摘 要： | 采用有限体积法,针对微弯分汊河段复杂的水流运动特点,建立了正交曲线坐标下的平面二维水流数学模型。以长江中游马家咀河段为例,进行了水面线、断面流速分布等的验证计算,验证结果与实际符合较好,表明该模型能准确模拟该河段水流运动规律,不仅可以用于该河段复杂水流运动规律的模拟,对其他类似河段数值模拟亦具有借鉴意义。

| Abstract: | Using the finite volume method, a plane 2-D flow mathematical model under the body-fitted coordinate system is established. Taking example for Shashi reach in the middle of Yangtze River, the computation results show the good agreement with the measuring data of the current velocity, water level. The model can not only be used to simulate flow movement in this complex reach, but also be practical and helpful in the research on other multi-branched meandering reach in the middle of Yangtze River. |
