摘要
凝析气输送属于两相流的范畴,对其求解可采用建立数学模型,然后用解析法求解,得到更为精确的结果。本文对凝析气长距离输送管道建立了稳态和瞬态模型,分别用了四阶龙格-库塔法和隐式差分法进行求解,并给出了求解步骤。实例表明,求解方法得出的结果与实测值吻合得较好。
The wet natural gas transportation belong to two-phase flow. The exact result could be obtained with analytic method base on the mathematics model. In this paper, the steady model and transient model for wet natural gas transport pipeline are established. And they are solved with Runge-Kutta formula and implicit difference method respectively. At the same time, the approach of solution is given. The results show that the theories and methods mentioned in the paper are available.
