摘要
针对分蓄洪区水流数值计算中的复杂边界问题,在传统笛卡尔坐标方法的基础上改用斜角笛卡尔方法.该方法能更好地贴近实际水边线,又能保留传统笛卡尔方法的优点.运用改进的分蓄洪区平面二维水流数学模型计算了湖北省白谭湖分蓄洪区洪水演进的情况.
Aiming at the complex boundary in the numerical calculation of flood diversion area, a bevel angle Cartesian method is adopted based on the traditional Cartesian method. The bevel angle Cartesian method has the merits of the traditional Cartesian method and can fit the actual water boundaries better. The flood routing in the flood diversion area of Baitan Lake, in Hubei Province, is calculated by the developed plane 2-D water mathematical model for flood diversion area.
