本文概述了与数值预报含颗粒湍流的任务相关的挑战和进展。综述了基于湍流闭合模型和直接数值模拟的数学方法。此外，还讨论了建立分散相输运方程的统计方法。综述仅限于不可压缩、等温、没有相变或颗粒-颗粒碰撞的流动。对改进一些重要关联的闭合模型提出了建议。
The paper provides an overview of the challenges and progress associated with the task of numerically predicting particle-laden turbulent flows. The review covers the mathematical methods based on turbulence closure models as well as direct numerical simulation (DNS). In addition, the statistical (pdf) approach in deriving the dispersed-phase transport equations is discussed. The review is restricted to incompressible, isothermal flows without phase change or particle-particle collision. Suggestions are made for improving closure modelling of some important correlations.
