| 摘 要： | 在天然气管道输送中,管内壁粗糙度和管道输送效率是影响管线压降的主要因素.TG-NET7.2仿真软件的计算程序中,粗糙度和输送效率的初值给定和调整是模拟用时和模拟精度的关键.TGNET7.2仿真软件基于粗糙度推荐科尔布鲁克(Colebrook)公式,未推荐调整输送效率时的摩阻计算公式.文中以川西气田常用规格管径为例展开研...

| Abstract: | In gas transmission pipeline,the roughness of internal wall and the availability ration will greatly interfere with the calculation of the internal pressure drop.It is key of TGNET program that gives the initial value and adjusts sensitive parameters,both of which have an effect on the inner surface roughness and availability ration.The simulation software TGNET7.2 recommends Colebrook formula on the base of roughness,but does not recommended any friction calculation formula on the base of availability rati... |
