| 摘 要： | 通过对液-固两相流在垂直等径流中流动的稳定性分析,讨论了v*、ρ*s、Fr及Re等无量纲参数对管束系统稳定性的影响。结果表明,这些参数可分为3类:数值增大时使系统趋于稳定的参数有v*、ε、e/D、ζ;数值减小时使系统趋于稳定的参数有ρ*s、Fr、u*、D*;数值变化时对系统稳定性影响不明显的参数有n、Re。

| Abstract: | By analyzing the stability of liquid-solid two phase flow in vertical tube bundle consisting tubes of same diameter, the factors which influence the stability are discussed by using some non-dimensional parameters. The tube bundle system tends to be more stable with parameters v*,ε,e/D and ζ increased or parameters ρ*s, Fr,u* and D* decreased. The parameters n and Re have no obvious influence to the stability of the tube bundle system. |
