| 摘 要： | 起伏多相流管路持液率计算方法在工艺计算中具有重要的地位,但目前只能靠经验或半经验相关式计算。计算水平管持液率,Eaton和DuklerII相关式较好;在下坡管段使用BB相关式,易导致持液率小于0的情况,一般不采用BB相关式计算持液率;在上坡管段,如果对应水平持液率大于0.309 7时,宜采用其它方法计算持液率或者在程序中将持液率大于1时自动赋1处理;计算起伏管路的持液率采用BBE、BBD和MBX相关式误差较小。

| Abstract: | Holdup calculation mainly depends on empirical or semiempirical correlation at present, so the prediction of liquid holdup in undulated multiphase pipelines is very important for technological calculation. Eaton and Dukler II correlation arethe best for calculating liquid holdup in horizontal pipe, In downhill pipe, Beggs&Brills(BB) correlations cannot be adopt-ed because holdup may be less than 0.0. In uphill pipe, if holdup corresponding horizontal pipe is greater than 0.3097,other correlation should be used. BBE, BBD and MBX correla-tions are considered as better correlations at the present. |
