摘要: 对固液两相流动进行了数值模拟。液相和固相分别采用 k- ε湍流模型和代数颗粒流( AP)湍流模型并考虑了液固两相间的相互作用。用此模型结合 SIMPLE- C算法对离心叶轮内的稀释固液两相流动进行了计算并研究了颗粒对流场的影响。计算结果同试验结果基本一致

Abstract: The turbulent liquid particle flow is simulated by using a two phase turbulence model,that is, the k ε liquid turbulence model and algebraic particulate phase flow turbulent model (i.e. \{ k ε AP\} two phase turbulence model).The interaction between the liquid phase and the solid phase is taken into consideration. By using the SIMPLE C scheme and the k ε AP model, the turbulent dilute liquid particle flows through a centrifugal impeller are calculated. The influence of particulate phase on the flow field is analyzed. The calculated results and the experimental results are in good agreement.

Key words: two phase flow, centrifugal pumps, turbulence models, numerical analysis
