同流环境多圆孔热废水排放数值模拟

各种热电、核电厂排出的热污(废)水在直接进入环境流体之前,以多孔口浮射流的形式释放污水并确保污水在排污口快速混合非常重要。精确的了解和预测多孔浮射流的特性与混合状况有很重要的意义。针对同向流动环境中多圆形孔口热水排放的情况,采用雷诺应力模型进行数值模拟,得到了不同流速比和不同射流温度下的流场和温度场、浮射流的轨迹线、轴线上温度和速度的衰减规律,并且分析了不同孔间距、流速比和射流温度对流场中流速和温度的影响。

NUMERICAL SIMULATION OF MULTIPORT BUOYANT JET OF THERMAL WATER IN CO-FLOWING

Before the thermal wastewater of the thermal and nuclear power plants intrudes into the environmental water,it is important to ensure that high initial mixing is achieved in the vicinity of the discharge structure by releasing the contaminated fluid through orifices and in the form of buoyant jets.Therefore,accurate understanding and predictions of the behaviour of a buoyant jet and its mixing characteristics are desired.With reference to the model of RSM,it is simulated the buoyant jet of thermal water in ...
