摘要:
结合河道水流及温排水的运动特性，从非正交曲线坐标系下温排水基本方程出发，采用有限体积法及SIMPLE算法离散求解方程，建立了基于非正交曲线坐标系下非交错网格的平面二维温排水数学模型．用该模型模拟天然河流电厂温排水运动的计算结果表明，该数学模型能合理反映河段电厂温排水运动。

Abstract:
Considering the kinematic characteristics of streamflow and cooling water, and based on the control equations of cooling water in the non-orthogonal curvilinear coordinate, a 2-D mathematic model for cooling water is presented with non-staggered grids in the non-orthogonal curvilinear coordinate.This model is used to simulate the movement of cooling water of an electric power plant in a natural channel. Calculation results show that the model can reflect rationally the movement of cooling water of the electric power plant.
Key words:  non-orthogonal curvilinear coordinate,non-staggered grids,cooling water of electric power plant,numerical simulation$$$$
