摘要: 正确处理流体力学方程中的对流项对环流的数值模拟起着重要作用。采用数值实验的方式,采用不同的对流项处理方法,模拟了厦门湾潮流场,并将数模结果与物模模拟结果进行对比,分析不同对流项处理方式对厦门湾区域流态模拟结果的影响,以此为依据提出适合港湾的对流项处理方法。Abstract: A convection term in the Navier-Stokes equations plays a important role to generate recirculation. The comparative experiment of numerical methods applied to the convection term are carried out to simulate the tidal flow in the Xiamen Bay. Results of the numerical experiment are compared with results from the physical model. The influence of different numerical methods for convection term on the flow pattern results in the Xiamen Bay is evaluated and the best scheme is proposed.
