摘要
高压燃气管道储气能力与两端压力和管长有着密切的联系。为了得到高压管道的储气量与压力和管长的关系,利用稳态仿真模型,采用四阶龙格-库塔法对模型进行求解,对求出的沿线压力进行线性拟合,得到沿线压力变化公式。结合储气定义推导出储气量与管长的关系式,并得到实例验证。从关系式来看,当管长等于最优管长时储气量最大。
The gas storage in a high-pressure gas pipeline is related with the two-end pressure and the length.To find the relationship between the gas-storage and the pressure as well as pipe＇s length,the method of linearization is used to realize the regulation of pressure along the pipeline and the formula for storage is established.Seen from the formula,there is a optimized value for the length of pipe.When the pipe length is equal to the optimized value,the quantity of gas-storage is maxmal.
