M—H平衡方程组的二阶分块三对角解法

The Second-Order divide-block tridiagonal algorithm for M-H balance equations set

本文提出精馏过程动态模拟中出现的质量、热量平衡方程组的二阶分块三对角算法,给出相应的递推公式,是对分块三对角追赶法的一种改进。

The Second-Order divide-block tridiagonal algorithm for Material (M) and Heat (H) balance equations set, appearing in dynamic simulation to a distillation process, is proposed. Also, a recursion formula of the algorithm is provided in this paper. It spreads the classic trdiagonal chasing-method.process simulation; distillation column; tridiagonal matrix.
