| 摘 要： | 本文针对大型火、核电厂温排水对湖泊、水库富营养化影响预测的迫切需要，建立了一套以改型分步杂交法为计算手段，对二维守恒型浅水环流方程及能量方程求解，在正确模拟流场及温度场的基础之上，继续求解单步一级生态动力学模型，并用单因素分析法考虑水温对藻类生长过程影响的计算模式．并结合一大型火电厂的建设，对该模式进行了验证和实际工作应用．

| Abstract: | A numerical model for predicting the impact of water discharge from thermal power stations or nuclear power plants on eutrophication in lakes and reservoirs is presented in this paper.The algorithm of the modified hybrid method of fractional steps is used to solve 2D conservation tyep shallow water circulation equations and energy equations.Based on the accurate numerical simulation of flow and temperature fields,using the single step one level ecological dynamic model,the influence of algae growth process resulted from water temperature rising is considered with the model of single factor analysis.This model is tested and put into application in the practical design of a large power plant project. |
