简要说明平面二维水流数学模型MIKE21的功能和应用情况,较详细地介绍该软件中的水动力学模块(HD模块)的计算原理和计算参数,以渤海湾大范围潮流场和天津港国际邮轮码头工程港池小范围潮流场数值模拟为例,展示该模型的模拟效果。结果表明,该模型可较好地反应实际情况。随着计算机技术的发展,数学模型和数值试验在科学研究、工程设计中的地位和作用不断提高,将水动力数值模拟全过程设计成软件包,配合良好的前、后处理工具,降低技术门槛,可使其通用性大大加强,是未来水动力数值模拟发展的方向。

Briefly introduces the fuctions and applications of a two-dimensional flow model-MIKE21 HD,and analyses the calculation principles and parameters of the hydrodynamic module in detail.The simulative effect of the models are shown through citing of two instances,one being the Bohai Bay as a tidal current field in large scale,and the other being the dock basin for the International Liner Terminal in Tianjin Port as the tidal current field in a smaller scale.The results show that the simulation results are basically consistent with the actual conditions.With the development of computer technology,mathematical models and numerical experiments will play more important role in scientific research and engineering design.Mathematical model software that includes the entire process of hydrodynamic modeling is designed to work with pre-and post-processing tools to reduce the technical threshold.The model will enhances its versatility greatly and will be the direction of future development of hydrodynamic simulation.
