| 摘 要： | 采用在缓坡上设置窄缝的方法,处理由于水位变动而导致计算域相应变化的动边界问题,提出了具有动边界功能的二维对流扩散模型的一种新形式,并将污染源作为移动源处理.所提出的方法已应用到渤海湾污染物迁移扩散模拟中,计算结果与实测值吻合良好.

| Abstract: | By using the slot method,the moving boundary problem caused by the change of the tide water elevation is treated.A 2-D advection-diffusion model with moving boundary is proposed,and the input pollutant is considered as moving source to meet the water level variation.The model given in this paper has been used to simulate the pollutant transport in the Bohai Uulf,the computational results are in good agreement with the measured data. |
