Abstract
Based on the theory of one-dimensional unsteady flow, a distributed parameter model of gas transmitting in pipeline was given. Then the model was solved with upwind difference formula, numerical simulations of the transmission of pressure waves in the pipe were also performed. Comparing the result of simulation with experiments, it was verified that this model was correct. And then the initial condition, such as the pipe diameter, air velocity, inlet pressure and the space step of simulation, was changed to simulate the different characteristics of the pipeline. Comparative analysis of the simulation results, the characteristics of the pressure waves of different waveforms under different conditions in the pipeline were obtained. The simulation shows that when using pressure wave to gas flow measure, it should use the waveform of half part of sine or square.
