摘要
基于脉冲响应,描述瞬变流在频域中求解的方法。假定管道末端阀门快速关闭,给出阀门处及管道任意位置处的压力和流量响应,提出了通过瞬态压力值(传递函数)的谐波分析,实现输油管道有无泄漏的检测。
Based on impulse response, the solving method of transient flow in frequency domain is described. If the valve is shut in the oil pipeline's end, the pressure and flow response are given at the value and any section respectively. Harmonic analysis of transient press values are given to realize the leak detection in oil pipeline.
