摘要: 本文应用Newton-Raphson技术求解精馏计算的三对角线物料平衡方程组.提出了一种新的块状三对角线矩阵法.本方法具有程序简单,对初值的选择要求不高,占用计算机内存少,计算偏导数少和快速稳定收敛等特点.
Abstract: A new computation procedure is proposed for multicomponent distillation columns processing non-ideal solutions. The Newton-Raphson method in whichliquid mole fractions are chosen as independent variables is used to solve the tridiagonal matrix equation, and a block tridiagonal matrix algorithm is developed. Successful applications of the new method to some non-ideal distillation systems are demonstrated with features of more insensitiveness to the initial values fewer C. P. U. memories, fewer partial derivatives more rapid and more stable than others.
