沿海港口电厂温排水、废水远区影响数值模拟

NUMERICAL SIMILATION OF FAR-FIELD INFLUENCE OF COOLING WATER AND WASTE WATER FROM A POWER PLANT

本文采用二维浅水方程和对流扩散方程,模拟沿海港口电厂温排水、废水排放后在远区水域的稀释扩散过程,并用ADI方法求解,对拟建厦门嵩屿电厂温排水、废水排放于附近海域的温度场及浓度场进行计算,结果表明以ADI方法建立起来的二维温排水数值模型来模拟电厂温排水在港湾河口稀释扩散过程是可行的,但存在固有的局限性,本文只适用于远区的垂直平均状况。

A two-dimensional shallow water equations and convective-diffusion equations have been used to similate the diluting process of cooling water and waste water from a power plant and the equations have been solved by ADI method.We have computed the temperature field of cooling water and the concentraion field of waste water from the power plant at Songyu,Xiamen.The results have been analysed.
