摘　　要：针对农业灌溉中对轴流泵性能的要求,为了更深入的研究该轴流泵的性能特性,研究了NACA0006对称翼型导叶的轴流泵性能,利用计算流体动力学软件Fluent,采用RNG k-ε湍流模型和SIMPLEC算法对该轴流泵进行数值模拟。通过对其进行数值计算和对比分析表明,设计工况下的数据值不仅与Fluent软件模拟的数据值相对误差为1.9%,并且应用Fluent软件模拟计算得到泵的性能曲线与性能实验的结果吻合较好,证明了在轴流泵导叶设计中,NACA0006翼型不仅结构简单、适用性良好,而且取得了更高的效率。For the requirements of axial flow pump performance in agricultural irrigation ,in order to research the characteristics of axial-flow pump further ,the performance of axial guide vane by NACA 0006 symmetrical air-foil flow pump was studied .Through the computational fluid dynamics software of Fluent and RNG k -εtur-bulent model and SIMPLEC algorithm ,the axial flow pump was simulated .The numerical calculation and com-parative analysis showed that relative error of data was 1 .9% with data stimulated by Fluent software under design condition ,and the performance curve and experiment results simulated by application of Fluent software were in good agreement .It proved that the design of flow pump in axial guide vane ,NACA0006 airfoil had sim-ple structure and good applicability ,and it could achieve higher efficiency .
