水平模型是的 2D 为关于冷却水的研究的主要数学方法之一从发电厂排出。在这篇论文,浅水方程在概括曲线的坐标系统和椭圆形的微分方程下面的 retransformed 被用来产生曲线的格子,在概括曲线的坐标的一个模型因此被介绍模仿 2D 水平冷却水。由有限体积方法,和非蹒跚的格子和简单算法管理模型 arediscretized 的方程被介绍在 discretization 期间简化程序。这个模型被用来在一条简化蜿蜒地流的隧道和一条自然隧道模仿冷却水的运动,推测结果显示这个模型能正确地反映冷却水的运动规则,它证实模型能在设计实践被使用。
2D horizontal model is one of the major mathematical methods for the research on cooling water discharge from the power plant. In this paper, the shallow water equations are transformed under the generalized curvilinear coordinate system and the elliptic differential equations are used to generate curvilinear grids, so a model in generalized curviline ar coordinate is presented to simulate 2D horizontal cooling water, Governing equations of the model are discretized by finite volume method, and non-staggered grids and SIMPLE algorithm are introduced to simplify the program during the discretization. This model is used to simulate the movement of cooling water in a simplified meandering channel and a natural channel, calculating results indicate this model can correctly reflect the movement rules of cooling water, which verifies the model can be applied in engineering practice.
