| Abstract: |
| 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 outfall of the cooling(water.) |
