基于CFD的轴流泵三维湍流数值模拟
Three-dimensional Viscous Numerical Simulation of Axial-flow Pump Based on CFD
摘要
Abstract
For further researching on numerical simulation authenticity and accuracy of axial-pump, both with its flow field characteristics, combined with a model pump data in South-North water transfer east project, the model pump were numerically simulated by using CFD software Fluent. Under the multi-reference frame ,both and RNG turbulence model with SIMPLEC algorithm were chosen, the Reynolds averaged N - S equation was dispersed by the finite volume method. The comparisons of external characteristics in simulation results and experiment results show that the turbulence model and 0 pressure inlet condition are suit for continuous simulation. By observing internal flow characteristics and researching on computation results, the relationship between pressure distribution and flow rate were described, the influence on internal flow by guide blade were also analyzed. It can be concluded that model is better than RNG model ,the average efficiency error of model is less than 3. 72%. When the inlet pressure is O,the numerical simulation with model is proved to be the best. This method showed its advantages in axial-pump's numerical simulation, it can help analyze axial-pumpS performance and can be a reference way for design.关键词
