摘　　要：采用计算流体力学数值模拟Flunet 6.3.26分析软件,选取标准κ-ε湍流模型和SIMPLE算法模拟了D450-60×7型多级离心泵节能优化前后泵内流道三维湍流数值,并对比分析了采集实际工况运行数据。结果表明,优化后的多级离心泵叶轮和导叶内部流场分布更趋均匀合理、效率高、节约能源,与实际吻合,并验证了该软件的有效性,为改型优化提供了理论依据。Based on the standard κ-ε turbulence model and SIMPLE algorithm,three-dimensional turbulence flow inD450-60×7 multistage centrifugal pump is simulated by using CFD analysis and numerical simulation software Fluent 6.3.26 under the circumstances of energy saving optimization.Compared the simulation data with the actual gathering data,the results show that the inner flow field of impeller and guide vane in multistage centrifugal pump is well-distributed and reasonable and the energy loses is less with the energy saving optimization;so,the efficiency is higher and it is consistent with the actual operation data.It also demonstrates that the proposed method is effective,which provides a theoretical basis for optimization design of multistage centrifugal pump.
