摘要
本文对电厂冷却水排入湖泊和水库后的热扩散过程进行了数学模拟,建立了三维扩散方程,给出了一维、二维和三维计算湖泊和水库中任意点任意时刻水温上升量的计算公式,并通过实例对一维情形的计算公式进行了验证,结果很好.
In this paper, thermal diffusion process of the power plant cooling water discharged into the lake and reservoir is simulated by mathematical method, three dimensional diffusion equation is built, one, two and three dimensional computational formulas for rising quantity of arbitrary point and arbitrary moment water temperature in the lake and reservoir are given, one dimensional computational formula for rising quantity of arbitrary point water temperature in reservoir is tested by applying example, the results are good.
