连续弯道急流的数值模拟

Numerical Simulation of the Rapid Flow in Continuous Bends

用准二维水流数学模型对桃河阳泉市区段约６ ｋｍ 长连续弯道中急流的运动进行了数值模拟。计算所得断面垂线平均流速分布合理，纵向水深计算值与实测值之规律及数值相符。

The quasi two dimensional mathematical model of flow is used to simulate the movement of the rapid flow in the continuous bends with a total length of 6 km in the Taohe river which goes through Yangquan City.The distribution of the calculated vertical average velocity is reasonable,the change pattern and numerical values of the calculated water depths in flow direction correspond to the measured water depths.
