摘要
输气管道的水力和热力计算是工艺设计和工况分析的关键。为提高输气工艺设计的速度及精度,基于流体力学基本方程建立了干线输气管道的水力和热力学微分方程组,采用四阶龙格-库塔法并结合VB编制程序对输气管线沿程的温度、压力和流速等参数进行了计算。计算结果与川气东送管道利川至宜昌段等多个管段的实际数据进行了对比,误差可控制在3%以内,吻合度高,符合现场工程实际,可为实际生产操作提供数据参考。
The hydraulic and thermodynamic calculation of gas pipeline is the key of process design and working condition analysis.Based on the basic equations of fluid mechanics,the equations of hydraulic and thermodynamic differential equations of the main gas pipeline are established.The parameters of temperature,pressure and flow velocity along the gas pipeline are calculated by VB programming using the fourth-order Runge-Kutta method.The calculation results are compared with the actual data of a few sections of Sichuan Gas Pipeline,from Lichuan to Yichang.The error control is within 3%,and the coincidence degree is high,which is in accordance with the actual project and can provide a solid reference for the actual production operation.
