摘要
根据油气混输的水力学模型,推导出了适用于管网系统的多相水力学计算的基本计算模型。该模型由节点连续性方程、环能量方程和两相流方程组成,经线性化处理后,得到了易于计算的通用方程和稳定性好的迭代过程。这种水力计算是进行管网计算和管网优化的基础。实例计算结果表明,该模型的计算稳定性和收敛性均较好。
Based on the hydrodynamic model of twophase flow in pipelines, the governing
models for hydrodynamic calculation of the oilgas gathering network are deduced. The models
are comprised of the node continuity equations, loop energy equations and twophase flow
model equations. The governing models are linearized and solved by iteration. These models
are the basis for calculating the parameters of gathering network and the optimization of
network. The calculation example shows that the governing models have a good stability of
calculation and convergence property.
