摘要： 在油气混输管道多相流模拟计算中,热力学模型是与水力模型相互耦合的重要组成部分,影响程序的收敛性和结果的准确性。通过对管段微元进行能量守恒分析推导了能量方程,该方程涵盖了焦汤效应、压力做功、剪切力做功、相变换热、管外换热等因素,是考虑全面的能量方程形式,可以比较准确地反映混输管道气液两相管流的实际情况。将模型嵌入到TPCOMP软件中,选取了现场实际管线英买-牙哈混输管道作为算例进行计算,并将沿线温度分布与OLGA 软件进行了对比。算例结果表明,该模型较好地模拟了管线的温度分布,相比TPCOMP原有模块计算精度提高,并与OLGA极为吻合,证明了模型的正确性。

Abstract: In the simulation of oil-gas pipeline multiphase flow,thermodynamic computation was an important process interacting with the hydraulic calculation,and it influences the convergence of the program and theaccuracy of the results.The form of the energy equation was key to the thermodynamic computation.Through analysis of energy conservation,the energy equation was derived.This new energy equation has considered many factors,such as Joule-Thomson effect,pressure work, friction work,phase change heat transfer,and heat transfer with the pipe wall.So it was an overall form of energy equation,which could reflect the actual fact of multiphase pipeline accurately.This model was incorporated into the TPCOMP,and a simulation was carried out with a practical pipeline,Yingmai-Yaha multiphase pipeline,and the temperature result was compared with OLGA.The results show that this model has simulated the temperature distribution very well.It is better than the original TPCOMP thermodynamic model,and the result is similar with that of OLGA,so the accuracy of the model is evident
