| 摘 要： | 本文建立了可模拟弯道中含污染物湍流的三维部份抛物型代数应力模型，以４５°弯道为例，针对左右两岸分别泄放污染物的环流非充分发展弯道流进行了计算，对所得的水流结构及污染物浓度分布进行了分析，结果充分反映出环流非充分发展弯道流中水流结构及污染浓度分布的特点。

| Abstract: | The 3-D turbulent flow structure and contaminant distribution in a 45-bend have been studied by the algebraic stress model of turbulence in this paper. The computeitonal results show that the calculated and experimental longitudinal velocity profiles are in good agreement. The calculated profiles of velocity, turbulent energy, dissipation rate,Reynolds stresses and contuminant concentration in the bend have been analysed, and the features of the turbulent flow containing contaminant in a bend with no-fully-developed secondary current have been obtained. |
