摘要
波浪是滨海电厂等电力工程中需要考虑的主要水动力要素之一,为了实现近岸波要素的准确计算,目前多采用数值模拟的方式,在近岸,特别是工程区附近的波浪模拟中,多采用时域解析的波浪模型(以下简称时域波浪模型)来进行计算。本文选取了两个具有代表性的近岸时域波浪模型,分别是基于Boussinesq方程的MIKE21BW模型和基于非静压浅水方程的SWASH模型,对两个模型的理论基础、计算流程、计算效率、后处理等方面进行了简单的介绍和对比,以期为工程中模型的应用和选择提供参考。
AS wave is one of the main factors that need to be considered in the coastal power plant. so it's an important task for the near-shore wave calculation. In order to achieve this goal, the numerical simulation method is usually adopted. The phase-resolving model is often used in the near-shore wave simulation, particularly near the designed project region. In this thesis, two representative phase-resolving models are chosen for inter-comparison: one is the MIKE21 BW model which is based on the Boussinesq equation and the other is the SWASH model which is based on the non-hydrostatic shallow water equation. On the basis of analyzing the differences of theoretical basis, calculation process, calculation efficiency, postprocessing of these two wave models, in order to give a good reference in the application of the models and selecting the suitable model in the practical engineering.
