摘要
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。
By introducing iterative method, mathematics models are established consisting of unsteady flow equations 1-2d and 2-2d in estuarjes. In the join of 1-2d or 2-2d mathematical modelling , an overlapping region is set up .The flow factors on the water boundaries of each subregion close to each other are provided by using the overlapping region. The coordination between subregions is obtained by establishing overlapping region, and calculating stability is improved. These two mathematical models have been applied to Jiaojiang Estuary and the results are good.
