摘　　要：为研究气相反应器空置状态配风流场特征,采用RNG k-ε湍流模型对其进行数值模拟。针对气相反应器流场的复杂性和局部多边形的特点,利用FLUENT的前处理软件GAMBIT来生成网格。对网格进行了网格无关性考核,确定了比较合理的网格数。实验结果展示了流场速度分布特征、流场湍流结构和压力场分布特征。经过对比反应器的静压分布规律数值模拟值与理论值,证实了所选的湍流模型是可靠的。本研究结果为气相反应器的设计与制造提供了参考。In order to study the characteristics of air distribution flow field of gas phase reactor in empty state,the turbulence model of RNG K-ε is used for numerical simulation.According to the complexity of flow field and the characteristics of local polygons in gas-phase reactor,the grid is generated by using FLUENT’s preprocessing software GAMBIT.The grid independence is checked and a reasonable number of grids is determined.The experimental results show the characteristics of velocity distribution,turbulent structure and pressure distribution.By comparing the static pressure distribution law of the reactor,the numerical simulation value and theoretical value confirm that the selected turbulence model is reliable.This research result can provide reference for the design and manufacture of gas phase reactor.
