摘　　要：建立了可模拟弯道中含污染物湍流的三维部分抛物型代数应力模型。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。分析了水流结构及污染物浓度分布的特点。The 3 D partial parabolic algebraic stress model of turbulence in a bend containing contaminant is established. The turbulent flow structure and contaminant concentration distribution in a bend with no fully developed secondary current are calculated. The calculated profiles of velocity, turbulent energy, dissipation rate, Reynolds stresses and contaminant concentration in the bend are analysed.
