摘要
本文利用欧拉差分格式对高压燃气管网非等温稳态数学模型离散,采用Newton-Rapshan法对多点边界值条件下非等温稳态数学模型进行求解。通过与Pipeline软件计算结果对比,最大相对误差小于6%,验证了方法的可行性。
The Eulerian difference scheme is used to discrete the non-isothermal steady flow model of high-pressure gas network. Based on the Newton-Rapshan method, the multi-point boundary value problem of the non-isothermal stead lfow model is solved.Compared to the result got from -calculation the Pipeline software, the error is less than 6% , and thus the feasibility of the method has been veriifed.
