摘　　要：为探讨弯管与导流片形式对流场品质的影响,基于RANS方程结合RNG湍流模型对水平循环水槽的弯管导流形式进行三维数值模拟,对出口处速度均匀性及弯管处压强分布进行比较分析。依据数值模拟结果,将非均匀布置导流片形式应用于实际水槽建造中,结果显示流场品质得到了明显的改进。The flow field of the circulating water channel′s curved pipe and guide wanes′ form was numerical simulated by the CFD method,based on RANS equation in conjunction with k-turbulence model,the effect of the form of guide wanes to quality of flow field was analyzed in terms of uniformity of velocity in outlet and the pressure field at guide wanes.The numerical results were used to guide the construction of a practical water channel,which use uninformed arrangement of guide wanes.The results showed that the quality of flow field is greatly improved.
