连云港潮流的数值模拟

连云港位于江苏省东北角,海洲湾以南,是我国五大重点港口之一。为了适应四个现代化建设的需要,连云港的整治和扩建具有重要的经济意义。在连云港物理模型进行试验的同时,我们开展了数学模型的研究。由于物理模型受到场所、设备、时间及劳力的限制,因此,寻找周期短花钱少的数学模型就势在必行了。因为数学模型在复演或预演水流现象时修改模型方便,能迅速提供多种方案供人们选择,因而它可与物理模型相辅相成,取长补短。

NUMERICAL SIMULATION OF TIDAL CURRENTS IN LIENYUN HARBOUR

Based on the physical model of the port of Lienyungang, flow patterns at spring, middle and neap tides(1978)have been reproduced using the ADI method.The computed results have been compared with those from the physical model,indicating good agreement.Furthermore, Computaions are also made for the possible effect on tidal currents of several proposed projects.
