钱塘江涌潮特性及其数值模拟

Characteristic and numerical simulation of tidal bore in Qiantang River

在钱塘江涌潮实测资料的基础上,分析了钱塘江涌潮高度、涌潮传播速度、涌潮流速、涌潮形态及景观、涌潮压力等涌潮特性.同时,应用基于KFVS(kinetic flux vector splitting)格式的二维涌潮数值模型模拟了钱塘江涌潮的形成、发展和衰减的全过程,复演了"交叉潮"、"一线潮"、"回头潮"等现象.通过对计算结果的比较分析,对涌潮特性有了进一步的认识.

Based on the field data of the tidal bore in the Qiantang River, the characteristic of the tidal bore is analyzed, such as the height, the propagation speed, the fluid velocity, the shapes and sights, and the pressure of the tidal bore. In addition, a 2D mathematical model based on KFVS（kinetic flux vector splitting）scheme is used to simulate the formation, evolution and dissipation of the tidal bore in the Qiantang River, and to numerically replicate the phenomena of the intersection, reflection of the tidal bores, and a thread-shape bore, which leads to more understanding about the characteristic of the tidal bores in the Qiantang River by analyzing the computational results.
