Abstract

A modification of the Quasi-Newton Successive Substitution method is presented, which is used to calculate phase equilibrium with a capillary pressure jump. To check the correctness, a calculation results of the considered method were compared with similar calculations using the Successive Substitution method. A low error of the method of Quasi-Newton Successive Substitution was obtained when calculating phase equilibrium with a capillary pressure jump.

考虑毛细管压力跃变的拟牛顿逐次代入法计算烃混合物相平衡的改进

摘要

提出了拟牛顿逐次代入法的改进，用于计算毛细管压力跃变的相平衡。为了检查正确性，将所考虑方法的计算结果与使用连续替换法的类似计算结果进行了比较。在计算具有毛细管压力跃变的相平衡时，准牛顿逐次代换法获得了较低的误差。
