摘要
A criterion for the onset of a shock wave motion of a gas column driven by resonance harmonic oscillations of a piston in a closed tube is formulated based on an analysis of the results of experiments and theoretical investigations. The validity of the proposed criterion in a broad range of parameters has been verified within the framework of numerical integration of a nonstationary system of narrow-channel gasdynamics equations written in a divergent form.
