摘要
针对天然气／凝析液长距离输送管道的计算问题，提出了理论的稳态综合水力学模型和热力学模型，并对水力学方程进行了修正，提出了具体的耦合算法。对计算进行了分析并将结果与PIPEPHASETM软件作了对比，发现本模型不仅可以准确地计算压力和温降，而且在某些方面更好地反映了凝析气输送工况的变化。
In accordance with the computation problems of natural gas/condensate long distance pipeline the authors put forward the theory steady comprehensive hydraulics model and thermodynamics model, revise the hydraulics equation and put forward specific coupling compuling method, analyse the method and contrast it with PIPE PHASE software. It shows that this model not only can compute pressure and temperature accurately but also can reflect the change of condensate gas transferring state better in several aspects.
