摘要: 近期研究表明,合理的初始分布能够大幅缩短气固提升管瞬态模拟从初始到达稳定状态所需的过渡时间。以此为基础,研究发现,若以时均统计的流场信息作为模拟的初始分布,则模拟能够很快达到稳定。然后,对影响过渡时间的各个时均流场参数(如压力、气固相速度、空隙率分布等)进行了敏感性分析,发现提升管的空隙率轴向分布是其中最为关键的因素。最后,利用EMMS(energy-minimization multi-scale)模型预测的空隙率轴向分布作为气固提升管动力学模拟的初始条件进行模拟,结果表明,计算很快能达到稳定,且预测的颗粒通量等参数与实验吻合较好。

Abstract: Recent studies have shown that a reasonable initial distribution can significantly reduce the transition time from initialization to reaching steady state for simulation of a riser.In this work,a series of simulations were performed to study the relationship between initial conditions and simulation efficiency.The results indicated that statistically-averaged distribution could be an effective initial distribution.Then,all the flow parameters for defining this initial distribution(i.e.pressure,gas and solids velocities,voidage) were investigated respectively for sensitivity analysis.It was found that transition time could be reduced greatly if a good axial distribution of voidage was provided at the beginning of the simulation.This finding was confirmed further by a hydrodynamical simulation of gas-solids flow in a riser with EMMS(energy-minimization multi-scale) model,in which EMMS model was used to provide a reasonable axial voidage distribution as the initial condition.The relevant results,such as solids flux,were in good agreement with experimental data.

Key words: initial distribution, voidage, riser, simulation, EMMS
