摘要
温排水问题为环境水力学的典型研究课题,研究温排水运动水域的流场温度场分布情况,无论是对温排水工程规划设计,防止热污染,还是对生态环境保护等都具有重要的科学意义。采用曲线坐标系下平面二维数学模型对连续弯道温排水问题进行了数值模拟,通过相同流速比下连续弯道中3种不同排放形式(左岸、右岸和中心排放)温度等值线图的比较,相同排放形式不同流速比时温度等值线图的比较,表明建立的数学模型能合理反映温排水运动规律,可以用于温排水运动的模拟。
The problem of warm water drainage is a typical problem in environmental hydraulics. To study the distribution condition in current field and temperature field of warm water drainage kinetics is of great scientific significance in respect to the design of warm water drainage engineering, the prevention of warm water pollution, and the protection of environment. A two-dimensional numerical model, which is in the curve coordinate, was applied to simulate the problem of warm water drainage in continuous bends. By comparing the thermoisop!eth chart of three different kinds of discharge-left bank, right bank, and center discharge-at the same velocity ratio in continuous bend and the thermoisopleth chart of different velocity ratios in the same discharge, it is indicated that the numerical model established in this paper can reasonably reflect the kinetic law of warm water drainage and can be used to simulate warm water drainage process.
