| 摘 要： | 对燃气管道不稳定流进行了研究，推导了了计算管内燃气流动的特征线法和公式。特征线法从基于流体力学基本原理推导出来的连续性方程、动量方程和能量方程出发，将难以求解的偏微分方程组转移为便于工程数值计算的等价差分方程组，从而解决了燃气管道中快瞬交流的计算问题。特征线法物理概念明确，数学分析严谨，计算精度高。 |

| Abstract: | As a result of the study of unsteady-state flow,a practical calculation method and formula of the characteristics method were derived from the equations of mass conservation,momentum conservation,energy conservation that were established according to the basic laws of hydrodynamics. The partial differential e-quations set difficult to solve was transformed to the equivalent difference equations set convenient for numerical calculation. Therefore, the calculation of quick transient flow in gas pipeline is accomplished. The method has explicit conception,rigorous mathematical analysis and high precision. |
| Keywords: | gas pipeline unsteady-state flow characteristics method numerical calculation |
