| 摘 要： | 河道水流的流态往往非常复杂。在设计水利设施的过程中，应综合考虑验证建造河道的水力因素，因此无法采用单纯的水力设计计算，需进行相应的物理试验来测定水利设施的合理性。随着计算机技术的不断提升，数值模拟技术得到飞速发展，数值模拟技术也逐渐被应用到水利工程中，由于数值模拟的准确性及便利性，数值模拟在水利工程领域变得愈加重要。该文详细阐述水流三维数值模拟的研究发展过程，总结水流模拟的优势和弊端，为数值模拟的发展提供参考依据。

| Abstract: | The flow patterns of river currents are often very complex.In the process of designing water conservancy facilities，comprehensive consideration should be given to verify hydraulic factors of river construction.Therefore，simple hydraulic design calculations cannot be used.Corresponding physical tests are required to determine rationality of water conservancy facilities.With continuous improvement of computer technology，numerical simulation technology has developed rapidly，and numerical simulation technology has gradually been applied to hydraulic engineering.Due to the accuracy and convenience of numerical simulation，numerical simulation has become increasingly important in the field of hydraulic engineering.Research and development process of 3D numerical simulation of water flow was elaborated，advantages and disadvantages of water flow simulation were summarized to provide a reference for development of numerical simulation in the future. |
