| 摘 要： | 本文采用Patankar 提出的控制体税法和乘方律插值分布,建立了无条件稳定、收敛的三级非恒定流水环境实时数学模型。文中提出了“分离表层水体"的方法,较好地解决了复朵的边界地形和自由表面的非恒定运动等问题;采用顺序解法节省了计算所需的内存量及加快了求解速度。该模型在珠江口东侧水域得到了广泛的应用,效果良好。

| Abstract: | A real-time mathematical model for three dimensional unsteady flow and Water quality is presented in this paper. A control-volume-based-difference method and a"power interpolation distribution" advocated by Patankar (1984) have been employed, and a concept of "separating the toplayer water" has been developed to solve the movable boundary problem. The model is unconditionally stable and convergent. Practical application of the model is illustrated by an example for the Pearl River Estuary. |
