摘要
利用有限元分步杂交方法,对胶州湾海域潮流场进行了数值模拟。考虑余氯在水体中的化学反应,利用前人大量实验成果选取余氯衰减系数,建立胶州湾余氯的二维输运-扩散模型,并将此模型应用于青岛市黄岛发电厂三期温排水工程,预测了温排水中余氯的浓度分布及影响范围,为电厂冷却水排放口邻近水域的生态环境保护提供依据。
The tidal current field of Jiaozhou Bay is numerically simulated using the split steps finite-element method. And then, the attenuation coefficient of the residual chlorine is selected based on a good number of experimental results. Finally, a two dimensional model of the transport and diffusion for the residual chlorine in Jiaozhou Bay is established. This numerical model is applied to the cooling water drainage engineering in the Huangdao Power Plant of Qingdao. According to this numerical model, the concentration distribution of the residual chlorine in the cooling water drainage and the area of its influence are numerically predicted, which can provide helpful reference for the ecological environment preservation around the ouffall of the cooling water.
