Application of fourier method to study propagation of compression shock wave in pipelines with damper

The transition problems from one mode of steady flow to another in a pipeline with constant gradient are considered. pressure value is set at the inlet section, and an air chamber certain volume installed outlet. Modeling process compression shock wave propagation elementary section was conducted according linearized quasi-one-dimensional N.E. Zhukovskymodel, damper considered I.A. Charny model. problem solved by method separation variables. It shown that increase damper, amplitude frequency perturbations decrease due transient process.
