摘　　要：以水泥生产中常见的原料立磨为研究对象,利用计算流体力学CFD软件来模拟分析立磨内部流场的动力学特性,模拟计算尽可能的考虑气固两相之间的相互作用.根据模拟结果,从速度场、温度场和粒子轨迹等角度去讨论和分析磨内的流场特性.并与实际生产情况相结合进行分析总结,这为今后原料立磨的进一步优化设计和生产应用提供流体动力学依据.This paper studied the vertical roller mill of the raw meal,which has very popular applications in the cement industry.Based on Computational Fluid Dynamics（CFD） software and considering the interaction between the gas-solid flow,the aerodynamic characteristics in the internal flow field of vertical roller mill is simulated and analyzed.According to the results of the simulation,the flow characteristics is discussed and analyzed from the contour of velocity,the temperature,the particle tracks et al.By combining the practical processs of the vertical roller mill,we analyze and summarize the flow characteristics,which provides the aerodynamic bases for the optimization of the design and actual applications.
