应用ADI法计算潮流污染扩散的数值分析

NUMERICAL ANALYSIS ON TIDAL CURRENIS AND POLLUTANT DISPERSION DUE TO ALTERNATING DIRECTION IMPLICIT METHOD

本支讨论的是应用ADI法计算潮流污染扩散的数值分析。数值模型是二维的(平均深度),扩散物质是恒定的。主要是预测水质变化的情况,研究结果表明,污染废水排入海区后,污染水浓度在排水口周围4KM^2以外已低于天然本底值。

This paper describes a numerical analysis on tidal currents and pollutant dispersion due to Alternating Direction Implicit Method,the numercal model being two-dimensional(depth-averaged),and the dispersive matter being conservative, which can only predict major trends of water quality change. The result of the research is as follows:whcn the Guangdong nuclear power station is on normal operation and after the pollutant waste water has been drained off into the sea,it is found that the pollutant waste water density is even lower then the natural background value just outside the area of about 4(?)round the water outlet.
