本文引用区域分裂法,建立了河口、港湾非恒定流一、二维联解的整体数学模型和二、二维联解的整体数学模型。在一、二维或二、二维模型的联接处,设计了一个重叠域,由此互为相邻子域提供水边界点(线)上的水力要素。重叠域的设置保证了各子域间的协调性,大大提高了计算稳定性。上述两模型应用于椒江河口,结果令人满意。
In this paper, the method of regional splitting is used to establish the overall mathematical model and the overall mathematical model of two-dimensional and two-dimensional co-solution for the unsteady flow in the estuary and the harbor. At the join of one, two, or two or two-dimensional models, an overlapping field is designed whereby the hydraulic elements on the water boundary points (lines) are provided to each other adjacent subfields. The setting of overlapping domains ensures the coordination between sub-domains and greatly improves the stability of computation. The above two models are applied to Jiaojiang estuary, the result is satisfactory.
