摘要
基于边界拟合坐标系,运用涡量—流函数方程和标准k-ε双方程湍流模型,通过有限分析方法对连续弯道的水流和污染物的扩散输移进行了数值模拟,计算了流场及岸边污染物排放的浓度场,并与实验室结果和有限体积法的计算结果进行了比较.
In this paper,based on fitted boundary coordinate system,the Ω—Ψ equations and the standard k-ε double equations’ turbulence model are adopted.Then,Finite Analytic Method is applied to the numerical simulation of the flow and the contamination diffusion-transportation.The flow field and concentration of the bank discharge of the meandering channel in laboratory are calculated.A comparison is made between the measured data and the calculated results by Finite volume Method.
